Back Space ??

I have a 64 Dart that I just inboarded my springs 3/4". The 8.75 rear is stock A body length. My thoughts are to run a 8" rim with a 5" backspace with maybe a DOT tire equivlent to a 245/60/15. Any suggestions?

I would suggest measuring the inside area first to see what you have exactly as far as width,pay close attention to the upper area due to the inner fender gets narrower towards the top of the inside area.There is a wheel site that explains how to measure the backspacing of wheels try this site and maybe check stockton wheels

Hope this helps,I know how to do it but it would take me two weeks to explain it and I don't typ that good! LOL
