Richard, what do you mean by third member? Can you be more specific. I am having a hard time finding the 55-62 chevy rear ends.

Will the original hub caps fit on a 5 lug rim?? Maybe I am too hung up on the 6-lug issue to keep the rims and hub caps original. If i can find a 5-lug that has the will accept the same rim size and original hub caps, then that work work. Any comments??
