Tom is right. The key word in the rules is "corporate". If you had a 56 Chevey stocker, any GM passenger car rear would be OK. Most would use a 12 bolt or an 8.5, strength and gear selection being the criteria for judgement. Your 57 Olds analogy is a little off base. Those rears are very strong but the gear selection nowdays is poor and they are heavy. I agree that in these days of purpose built stockers, the rear end rule is one of our "stupid" rules but the present rule beats the original rule hands down. Back in the day, the Ford guys got to use the 9in, the Mopars got Dana's and 8 3/4's and the Chevy guys got.....you guessed it, the Chevy dropout. As sticks were the transmission of choice, you can imagine the result. TT
