When I did mine, what I thought would work ( by measuring) did NOT work with that size wheel on it....Have you all seen these things before?

How to determine wheel size and backspace with the CCTek Wheel Tek tool
Determining the proper size and wheel backspacing for a new car build can be difficult. Enter the CCTek Wheel Tek tool.www.motortrend.com
I've seen a couple of different makers. Seems like it should work pretty well. Limps post reminded me of it.
67 Dodge coronets have a very small rear wheel well that gets smaller as more of the tire fits into it.. So trying some different sizes wheels ( mostly different back spacing) saved me some money...
I SQUEEZED some 8" wheels into the rear of mine that I had to have made with a custom backspace... I always thought later I would have just stuck with 7" like I had on the front....
