Q: Ralley II Wheel Code
Does someone know the correct codes for Rally Rims? Specifically, I heard there was a different code for rims on drum versus disc.
A: Check out the following WEB site by Richard Rauch:
Rich’s Pontiac Server http://pontiacserver.com/wheels.html
It is a fairly comprehensive page dedicated to pontiac rims and codes.
A: Parts book published in 1971 says 1967 used JA for disc and JC for drums 68 was JC for all. Try and figure this one out. All the parts for disc were the same for 1967 and 1968 so what made the difference I don’t know. A-body was just as confusing. I have several sets of JA and JC wheels so I m going to measure the offset of both. You can post this info if you want to.
A: The correct Rally II wheels for 1968 Firebirds with Disc Brakes is “JC”. References: 1968 Service Manual, 1968 Parts Book, Broadcast Sheet ((I’ve also verified this and several original, unrestored 1968’s)). At some point, someone started this (JA in 1968) ‘technical error’ while refering to the 1967-1968 GTO and 1967 Firebird.
A: Still dont have a clear idea of why 67s used two different RallyII wheels, one for drums the other for discs. Want to remind everyone that the code is at the valve stem not inside the rim. Ive seen some stamped with JC inside the rim and have a different code at the valve stem.
