here is some info off the top of my head...

All 65 and newer c bodies, pinchers, midsize pinchers, have 5x4.5 bolt pattern, early drum brakes used 14" and all disk cars used 15" (with a hub bore larger then fords)

64-66 and possibly older imps have 5x5.5 bolt pattern all using 15" wheels(with a very large hub bore)

67-73 Imps used 5x5 wheel pattern all using 15" wheels

I have used lots of rims on my shockers and y framers over the years, personally had the best luck with the stock ones. The rally wheels also work very well and look better. Ford wheels need the centers cut out alot making the wheel tend to bend easier. Aftermarket spoked wheels usually (not always) stick out further cause issues front and back. Also some of them are much stronger and thicker then factory, in turn it tends to break your car instead of allowing the wheel to bend some.

14" wheels will not go on disk brake equipped c body cars, you can remove the calipers in the front and they will fit, but some of the first gen chrysler 14'' c body wheels have a very small hub bore much like a ford. 

Steel Jeep wheels like on the Cherokees. They're 15 inch, and sorta look like an SS rim.

hole in the center is too small for most chryslers and have to cut a good chunk out

We cut the center out anyways, cause we put a uni-lug center in, never tried with just stock center. But that's good to know!
