Vintage American Racing Wheels

[69 Post Sedan]

For a Chevelle, the rule of thumb is divide the width of the wheel in half then add a half inch.

So,to fit correctly, a 8-1/2" wheel would need have a 4-3/4" backspacing.

I have 15X8 Corvette rally wheels on my '69 Chevelle and they have a 4" backspacing....and it really should be 4-1/2"....but they do fit.

Hope that helps, Kurt

I have no idea if the 8.5's will work on the back of the Chevelle. The 7's should be OK on the front. I hope this helps. </div></div>

Do the 7's really have more backspace than the 8.5's, or are those numbers reversed?

The 7's really do have more backspace than the 8.5's. I also have sent you a PM
