Boss and Mach Info

In the restoration of my '70 Mach 1, I'm finding I have to dig through lots of different resources to get the info I need.
By putting what I find in one place, hopefully I can make it easier for others. {and possibly in my restoration of a future Boss 302?}


A very helpful source of information has been looking over low mileage original Mach 1s, such as Rick Schmidt's 4900 mile specimen.

Body

There were two kinds of Mach 1 side moldings used, the early moldings had removable 'Mach 1' letters on the front fender molding, the later molding was cast one piece, letters and all.

Early molding on left, later moldings on right. I don't know the changeover date yet, but I'll post it when I find out. My December 1969 Mach 1 has the early style, which I restored and are on the car. The picture of the later one-piece moldings are of the set I bought on ebay.


The following was copied from the November 2004 MCA Mustang Times 'Judges Corner'
and was written by MCA '69-'70 Mustang and '69-'71 Boss Gold Card Judge Jim Cunningham.

'69-'70 Mustang antenna
The correct antenna for '69-'70 Mustang is a round mast with a black teardrop shaped plastic
tapered insulator extending into the cast rectangular four-hole mounting flange. They were supplied
by the Ward Antenna Company of Amsterdam, New York in master packages of 50 and were shipped in the
trunks of cars for installation by the delivering dealer. The part number is C9ZA-18813-B, and the
correct service replacement were C9ZZ-18813-B.

Textured paint:

In this excerpt, Perkins was referring to a Boss 302:
"...This paint was applied to hood, taillight panel, decklid, and panel below the back light. This paint was Ditzler DDL 92812 or DDL 9381, and is no longer being produced..."

Bob Perkins {from Perkins Restoration, North 3123 Highway 16 & 26, Juneau, WI 53039} says that Dave Walden from ECM Automotive (636) 207-7767 has some made and will sell in quart quantities.

Another source I have found for textured paint is AutoBodyDepot 858-695-2900, and they sell on ebay and maintain an ebay store . Their description reads as follows:

Low-gloss paint: This paint was used on shaker trim rings, louvers, and the taillight bezels on the Boss 302s.

The hood blackouts and stripes on the '71 Boss 351s as well as the '71-'72-'73 Mach 1s were all low-gloss black or argent. There are details in the August '98 and June 2000 issues of Mustang Monthly.

I found it interesting that in the Bob Perkins column 'Resto Roundup' in the March 2003 Mustang Monthly, someone wrote in to say that a good match for the black textured paint is BASF Glasurit Color Max 2 Solid, Paint #SFA3450.

On '71-'73, the hood blackout is low gloss black with no texture. The rear spoiler option is low gloss textured black, like the '70 Mustang hood and spoiler. {also from March 2003 Mustang Monthly}

The Buck Tag is located on the core support near the right side fender extension on Dearborn built '70s, and on the top of the right side fender apron by the hood hinge on San Jose cars. Not all cars had buck tags, in fact my two Dearborn built Mustangs and San Jose build Mach 1 have no tags or even traces of having had them in the past.

The front fenders on the Boss 302s were rolled for tire clearance, the rear quarters were not.

Here are the dimensions for the paint treatment and stripes on the hood:


The Cobra Jet scoop. {What this graphic shows incorrectly is the hood scoop placement. On my original Mach, the rear of the scoop is located exactly 1/2" {.500"} from the rear edge of the hood.} There is some references to some Mustangs with the Cobra Jet scoop having what is referred to as the 'Dearborn' stripe.' The 'Dearborn' stripe referred to Machs with the non-shaker scoop {Cobra Jet scoop} and on those the stripe goes over the cowl panel all the way to the windshield. On my San Jose built car {and I think the Metuchen NJ Machs too}, the stripe stops at the end of the hood, and doesn't run over the cowl panel.


Here are the dimension for the '70 Mach with shaker scoop. Notice how the back of the stripe is rounded and returns on opposite side.

Most '70 Mach 1s had black stripes, but some came with white, most the black or other dark colored cars had the white stripes applided to them. For this reason Ford supplied replacement engine callout numbers that were black and white to accomodate both stripes. So if you see a Mach with these callouts, you know the car has been repainted:

Here's an example:

I prefer black:


'70 Mach 1 dark argent paint treatment.

The '70 Mach 1 uses a darker charcoal argent {gray} paint on some of it's trim, namely the grille, die cast rocker trim, and honeycomb taillight panel trim. Rick Schmidt at NPD has had the color researched and correctly reproduced and sells it as part number AP-GPA.

On the grille the cast aluminum housings of the sport lamps are semi-gloss black where not chromed. The plastic trim is the same dark argent color as the grille, as are the plastic trim surrounding the headlights and the painted areas of the lower grille molding and eyebrow moldings on the headlight extensions. This color is also used on the die cast aluminum rocker panel moldings, with the exception on semi-gloss black in the recessed areas of the 'Mach 1' letters on the front fender moldings. If the Mach 1 is equipped with Sport Wheel covers, {see example below} they are also painted this shade.


The Shaker hood scoop.

Shaker details:

'69 Boss 302 snorkels have C9ZF-9D626-A stamping underneath in white ink.

The ribs on a shaker scoop are painted argent. Some folks paint the shaker semi-gloss black then sand the ribs clean, but that's not accepted by MCA judging if that's a concern.

While all the shaker scoops use the same top and midplate, the bases vary due to different carburetor heights on the various engines and also their differences in valve cover air source locations.

Spoiler Details:
Both measurements provided by Rick Schmidt from National Parts Depot.

{I used these dimensions to install my spoiler on my Mach and it came out perfect.}

'69-'70: The rear wing measures 7 5/8" from the front edge of the deck lid to the front edge of the pedestal (not the rubber pad, but the pedestal itself).

'71-'73: Measuring from the rear edge of the decklid to the rear edge of the pedestal GASKET, mine measures right at 4 inches. 7 5/8" inches from the front edge of the pedestal gasket to the front of the decklid. Centered, obviously. Be sure you don't mount the spoiler backwards on the pedestals, I see that so often, one of those things at shows you see that drives you nuts. At the tips of the spoiler, the rear edge should be angled forward, and the leading edge is straight.


Electrical

Correct headlights on a '70 have TS in raised letters on bottom. {stands for the manufacturer Tung-Sol}


'70 Mach 1 tailpipes

There are two types of tailpipe extensions for '70 Mach 1s with dual exhaust, the oval tips and the square tips. I was always under the impression that only the 428 cars got the oval tips, but I've noticed both the 'Mustang Recognition Guide' and the '1970 Mustang Illustrated Facts Guide' state that the oval tips were used on both the 428 and the 351C 4V cars. I think the cars got both styles, perhaps depending on supply or build plant.

These are the ones I have, they have a Ford part number of D0ZZ-5255-A. They are squarish and the ends aren't rolled. Both sides seem to use the same length pipe:

These are the oval ones, They have a short and long side and the ends are rolled. I've seen part number stamped on the long pipe as DOZA-5C203-C or DOZA-5C263-C, and the short pipe as DOZA-5C262-C:


These oval tips are in demand currently, NOS tips are going on ebay for around $600-800 a pair. NPD has just started carrying reproduction tips for $350, and they are stainless steel, as opposed to the original tips, which were chrome plated steel tubing. The NPD tips should last a good long while.

All these tailpipe extensions are used on four barrel equipped cars with dual exhaust and cutouts in the rear valance panel for the tips to exit.
Mach 1s with the 351W 2V got a single exhaust and used the standard Mustang rear valance.


Wheels

The standard wheel used on the '70 Mach 1 was a trim ring and hub equipped stamped steel wheel painted dark argent.

Kind of looked like a Chevy Rallye wheel to me.

Magnum 500s: There were two types used on the Mustangs.

The small hole center Magnums {C9ZZ-1007-D} were used on the '69-'70 Boss 302, '70 Boss 429, and '71 Boss 351s built before April 2, 1971. The paint ID code for this wheel is two white paint daubs. The early Magnum 500s used on the '69 Boss 302 had argent painted centers. All later Magnums were detailed in semigloss black.

The large hole center Magnums {D1OZ-1007-A} were used on Boss 351s built after April 2, 1971 and all '71-'72 Mustangs with the Magnum option.

You sure couldn't tell it by going to car shows, but most Boss and Machs didn't come with the Magnum 500 wheels originally, they were added on afterwards. In 1969, only 467 Mustangs got the Magnums, in 1970, only 2634 did.

Sport Wheelcovers: These were what most '70 Mach 1s came with from the factory, along with 14x7 steel wheels. Many people confuse these for the similar type wheelcovers used on '71-'73 Mustangs. The differences are that the Mach 1 covers have a deeper trim ring section to accommodate the 7" wide wheels and the cast centers are painted charcoal, while the '71-'73 Mustang type are painted bright argent in the centers and have thinner trim ring sections to accommodate the 6" wide wheels. Boss 302s got these in 1970, too except on 15x7 wheels. Those are pretty rare, but still pop up on ebay from time to time.


Engine/Drivetrain

Original carburetor for '70 351C 4V with automatic and w/o A/C was D0OF-C Y or AC 4300 Autolite. The MPC lists the C, Y & AC suffixes in the same column with no other details, other than with C/M (FMX), C-4 and IMCO, w/o A/C. CFM is 605.

For underhood paint, one thing I was relieved to find out is that San Jose built cars like mine were painted entirely semigloss black, unlike the Dearborn and Metuchen cars which got slop gray {a combo of paint Ford threw together from remants of the paint shop which usually ended up a dark shade of putty gray.} on the shock tower struts and hood latch paint. I was relieved because I think the all semigloss black looks much nicer and is sure easier to accomplish.
