if you don't find one for a while my brother's & my '73 currently has a 3.08:1 in it from a late 70's car (it may have even been a disc brake rear end); The plan is to use his original (2.73:1 open diff) rear with a 3 series posi pumpkin and a 3.42:1 gear set - and sell the 3.08:1 setup as it is right now.... so just keep this in mind.
