I am going to put long wheel studs in the disc brakes on my 67. The problem is the .615 knurl studs don't touch the place where the knurl is on the rotors. The knurl on the studs quits before it touches anything. I thought about the .685" studs but the hole is too small for these without drilling it bigger. Has anyone put long studs in 67 rotors before? If so what studs did you use? Thanks.

These are the ones that I have and they don't work. If the knurl on these studs were 1/4 to 3/8 longer they would work. Right now they don't touch anything.

Been there done that. NO such thing available. You either have to fake it or drill the hubs for a larger size.

Drill them small and press the big ones in.

I think ARP's are like .625" on the knurls. Would this come closer to fitting?

I know for the Granada hubs/disc's I had to get the small knurls that are listed for the Franklin disc brake hubs. It was about .563.

MattN,
I ran into the same problem with my '69FB. I ended up installing the ARP studs #100-7707; They are 3" long; with 0.625" knurl, ? " X 20 thread. The down side: the 10 studs from Jeg's cost me $135!!

Say what? $135? Did you have to end up buying new rotors too? I just returned 2 sets of those studs to Jegs last month when I was in Ohio and they were only 10.99 a set.

Yep, I'm pretty sure of the high cost! Now I suspect that price included shipping, but that was still WAY STEEP and something you don't forget too soon!

Typically, I take my purchase info off of the invoices and imput it into the Racecar Journal on my 'puter.....I did buy the studs a few years ago....

No, that cost was only for the studs! I'm using the '69 OEM rotor discs.

Check the studs out at:
http://www.arp-bolts.com/media/pdf_files/dr_whnasspdr.pdf

I see ARP is calling the #100-7707 part, "Ford, front disc brakes, Early" and also say they're only a 0.615" knurl(?); I can't explain that. Could it of been that I measured across the "top" of the knurl and that ARP may measure the dia. from the "bottoms" of the knurls? Does that seem to be reasonable... the difference between 0.625" and 0.618"?

I read that when I was searching for studs for the Granada rotors. I even bought the 7703's, took them back and got .618's (7707) but the Granada disc take the 7706's.

I do believe the mearsurements are taken on the knurl itself. And I believe there is actually a different drill size used between the two.

Well I bought the .685" studs and a 43/64 drill bit. Looks like it is going to work just fine. If you don't drill too deep, just enough to clear the bigger knurl, you can reuse your old studs if necessary. Matt.
