I’m building a street/strip camaro and plan to use a 12-bolt rear. I got the rear from the owner of a highly modified ’67 camaro used only for drag racing. He uses Dana rears, and haven’t used the 12-bolt since 1972. Now I got the bare 12-bolt housing, axles, and the original 4-series carrier. The 12-bolt is in great shape, even has that weird anti-hop bracket used on some ’67 camaros. My questions are: Are these rare? Would it be a shame to cut it up and use C-clip eliminators? If so, what's it worth? I feel a little quilty chopping the ends off.
