68 steel wheels

[Jim R.]

Can anyone tell me what cars other than the 68 corvette came with the 7x15" Rally wheels.

To my knowledge, they were unique to Corvette

Jim,

The 1968 Corvette 15X7 rally wheel is stamped "AG".

The 1969 Camaro Z28 and 1970 Monte Carlo 15X7 rally wheel wheel is stamped "YH". This wheel was replaced by a similar 15X7 rally wheel stamped "FW" (and then "Z") that was used on the 1971-1977 Monte Carlo.

I believe that the difference between these wheels is the offset.
I have a "FW" 15X7 rally wheel that measures about 8 1/16" or 8.06" (gross width). The backspacing measures about 4 5/16" or 4.31". The offset would be 4.31"-4.03"=0.28" or about 9/32".

Joe,

According to Colvin's "Chevrolet by the Numbers" books the "AG" wheel has an offset of -0.28" and the "YH" & "FW" wheels have an offset of 0.30" (I was off by 0.02" measuring my "FW" wheel).

The net difference would be 0.58" so if your put a pair of "YH" or "FW" wheels & tires on a 68 Corvette the track width would be 1.16" narrower then with the original "AG" wheels. I believe that this is correct.

There is a catalog listing for 1970 Camaro with SPH 350 using a 15 x7 wheel also, part #3983044

Yes, you're correct. I mis-read the Corvette offset as POSITIVE when it's actually NEGATIVE. The other wheels are POSITIVE. So, there is no other original Rally Wheel with anything near the 1968 Corvette wheel off-set.

By the way, I deleted my previous post so that the inaccurate information I provided does not find its way into the archives.

Ray,

The 70 Z28 wheel (GM # 3983045 w/"AU" code) is not a rally wheel.
