Yes, there is a difference in rimblow wheels. Most people don't even know it. The a-body wheel has a different "dish" to it than an e-body. This was pointed out to me a couple of years ago when I had one(a-body) for sale. I'm not sure which offset is correct for an e-body but my brother has an original one off of a Challenger R/T that is correct for e-bodies. The difference is hardly noticeable unless you were to put both wheels next to each other. It's probably only about 1/2" difference. Most guys will say that they're the same, but they're not. They even have different part numbers. I'll have to check with my brother for the correct dimension and part number. Jim
