need to know back spacing

I have a 68 with a stock rear axle. I want to put on 15x8 inch summit d-force mags with 275/60r15s and I would like to know if anyone could tell me what the back spacing should be. Also what would be the maximum width rim that I could run up front and what should that back spacing be. I would like to go as wide as I can without rubbing fenders and frame. Can I go with a 15x8 rim up front also. Appreciate any help I can get.

I saw in a thread where you could go with a 5.5" back spacing on the back with no rubbing. One guy went with a 5.75 back spacing but could not ride a passenger and one in the back seat. Up front is 4.5" back spacing. I hope this helps.

Carefull on the backspacing recomendations, wheel size makes a big difference. With a 17" wheel 5.5" bs might work because the lower shock mount is inside the wheel opening but on a 15" wheel the wheels inner rim would probably hit the shock with 5.5" bs...

Go through the sticky threads (by year) in this forum and see what others are running...

Re: need to know back spacing

Thank you Doug. Thats the size I want on the rear of my 68.Also what size are the rims you have up front and what size tire? Also the back spacing on those if you have it. By the way I am painting my car in brandywine over galaxy gray House of Kolor. Would that be a candy color on your car,its very sharp looking. Thanks again Scott.
