I hear you OldSub.. Hadn't thought about that.. When I was in the process of changing my rear end out my goal was to keep my 6 lug pattern.. My only concern was having the 12 bolt pumkin as oppose to the stock 10 bolt that came with my 62.. The 12 bolt third member pumpkins are easier to maintain and swap R&P's..
So I was only looking at 6 bolt lug pattern rears..
