I've read most of the threads on wheels and backspace. I've verified that an 8" width wheel will require a 5" backspace. I tried an 8" Crager SS wheel with a 4 1/4" bacskpace and P275/60 x 15 tire and it would not clear the outside of the wheel opening with upward axle travel. A 5" backspace wheel likely would clear. A P225/70 x 15 on a Crager 7" wide wheel with 4 1/2" backspace easily clears. The problem is the only 8" width wheel I can find with 5" backspace is the factory type Rally I wheel from Wheel Vintuques. Not a bad choice but I would really like a more aggressive period wheel such as the Crager or American Torque. However on their websites I can not find an 8" width wheel with 5" backspace. Anyone know of a wheel source with 5" backspace?
