Found some wheels and need to know what I really need for my 1970 GTX. I do not understand all the back space stuff. The ones I am looking at say Cragar SS wheels with 3 5/8 backspace. Will these work on the GTX? They are 15 x 8 wheels.



I have 15x8 Cragar SS wheels with 4 1/4" BS on the rear of my 70 GTX with 275-60 tires. I can't say if the same tire on a wheel with 3 5/8 BS would fit but I wouldn't think a narrower tire like a 245-60 or 255-60 would be a problem.
