I'm planning way down the road of course, but my 71' Roadrunner originally came with the 14 inch magnums. Of course they have long been lost for some time now.

I was looking at wheel vintique's 18 x 9.5 inch magnum wheels but am a little lost as far as backspacing without having clearance issues. These 71' b-body cars have some very large rear fender wells and can fit a pretty large wheel.

So this is mainly in regards to B-body owners. What was the factory backspacing on the original wheels? Is anyone running an 18 inch wheel with 5 inch backspacing on your b-bodies? Any pics of these magnum wheels on your cars is much appreciated.
