I have a set from a 1968 Coupe. They have C7Z part numbers - for a 67? The car is definately a 68', has front and rear side marker lights, rearview mirror on the windshield, correct qtr panel trim, etc. The catalog's show 1967 window regulators being different from 1968, is there a difference? Any idea why these have a C7Z part number if they are? Thanks for any responses, just curious.

So am I. The handles were different but never thought it made a difference in the regulator. Can't think of any but the catalog DOES show different numbers.

According to Osborn's '68 body manual, the '68 regulators had a C8Z assembly number. However, I can't find any part number. I know for a fact that some C8Z assemblies used exclusively C7Z parts. I have three sets of '68 doors, so I'll take a look at the regulators if no one answers you soon. Is the part number easy to find?

The part number was on the small end, can't remember off hand if on the main assembly or on one of the arms. It is easy to find though.

Well, I just checked the risers on two doors from a latish '68, both original as far as I know. (I took them from a rusted out but unrestored car.) When I say "latish", it had the post-February reflectors at the back. Anyway, without removing the risers I can see C7Z part numbers on both of them.
I see from the NPD catalog that '67 and '68 risers are supposedly different. Maybe Ricks will stop by and explain why.

This car had the rectangular rear marker lights, so it is an early model. I had considered that as a possibility. The doors are original to this car, the door tag matches the VIN on the dash and title, so they are not from a 67'. I thought of that as well. Now I have the rear qtr window regulators out. They show that 65-67 are the same, but mention nothing about the 68's. They skip 68 and go right into 69-70's in the catalogs. 68's are unique for that one year only? Getting more curious.....

If my memory serves me right, I believe that the main difference between '67&'68 is that on one year, the rollers are replaceable as a seperate item and on the other (I think '68) the rollers are part of the assembly and must be replaced as such. If anyone can confirm that this is the only difference and that they are otherwise interchangeable, it would be extremely helpful as the regulators for '67 seem to be easier to find and I have a '68 Coupe that needs 3 out of 4 replaced. I hope this helps more than confuses.------------------

Re the 1/4 windows: The 65/66 has smaller rollers than 67/up. Am not sure about 68(without looking) but the 67 is NOT replaceable. I have 67 1/4 windows and backing plates in my 65. The original windows were damaged. Going to a Mustang shop this afternoon, will try to get an answer for that

I am in the process of swaping doors: my original is C6 and the replacement door(from a 68 coup) is stamped C7. I am using the original regulator, wing assembly stamped C6. Both set ups look the same eccept the glass in a fastback is rounded and the coup is squared. I haven't closed up the door yet the window needs alignedbut it seems to work fine!

Didn't we run into this before and find the difference is the length of the window crank shaft to accomodate different thickness in door panels?------------------

That applies to 65-6 door panels with and without pony interior. And that part is not on the regulator itself.

I took some doors off a 67 once and put them on a 68. I don?t know if the 67 had the deluxe int. but the shat that the window crank goes on was longer than the 68.
