My car is all stock 70 Swinger. There is roughly 3/4 inches from the tire to the factory inside wheel lip with molding.
Hey Klingon- they have to have tape measures up in Mt Albert somewhere.All I know I have an 8 3/4 rear end with 10 drums
I have 245/60/r14 on standard 14X7 Rally rims, not sure of backspace measurement. They fit no problem, the speedo is off a few mph but not too bad. You need to find out the diameter of current size tires and compare to new size. I looked up standard G78/14 which compare to 225/70/14 that have a diameter of 26.50 inches. the 245s have a 25.60 diameter.
