I havent't been able to find a part number other then the one Global West uses to get wheel studs.
I have found a # to get locally to convert from the metric studs the 1LE rotor uses to 7/16".
Dorman #610-114
NAPA #641-1560
The specs are 7/16X20 x 1 21/32" long.
The 1LE rotors need to be drilled oversize to use these studs. My machine shop drilled them to 9/16"
The original studs from my car are too small at the knurl to use.

Once I had the numbers I had no idea what they originated from. A call to Dorman helped that they were from a 64 to 72 Pontiac. Doing some reference work from parts stores on the web I found they are from a 69 GTO w/ drum front brakes. graemlins/hurray.gif
So there you have it. graemlins/beers.gif

Whats the knurl size for the studs?

Hmmm, might have just solved my "parts at your local auto store" dilema for the C5 swap graemlins/beers.gif

Joe, they are too short. Need at least 2" studs, I do anyways-my 2" cap screws leave about 3/4"maybe more to thread a lug onto.

Good eye Dennis. Might have to do some more digging to see if they have a longer version.
