if you get the backspacing just right, you'll be able to fit the largest tire possible. any larger than that, and you've got trouble, mister.


for what is the good life if not doing things thoughtfully?

I have a 73 with cal trac mono leafs, I put a 1/8 in spacer between the spring perch and the spring pocket on the front of the spring. I can fit a 30X9 Hoosier radial in it with a 15X8 wheel with 4.5 back space.

thanks for the info. for now i will be running the mopar 002/003 super stock springs.so it sounds like my weld drag lights that are a 15x8 wheel with 4.5 back space and some M/T 275/60/15 E/T street drag radials would fit then? got any pics of your car? thanks Mopar65
