Thanks! the back rims are 15x10 3" backspacing. The fronts are 14x6. I'll have to check the tire sizes tonight. I plan on going with cragars in the back with 4 1/2 backspacing. The centerlines came with the tires. The front I will eventually go with rally wheels with the polished trim rings and 1970 centers and polyglass tires. Looking at back in the day pics, that is what they did. They would replace the back tires with aftermarkets and retain the stock front tires.
