Ok here's the deal. I recently bought a whole 1995 Cobra brake assembly and a 1995 Cobra rear axle with a 3.73 gear to put in my 91 GT. Unfortunatly I'm really having a craving for those 3.73s but I don't have the funds right now to get the rest of the parts for the 5 lug/Cobra Brake swap. So what I'm thinking now is I'll take the rear disc parts and five lug axles off the Cobra diff and swap in my 4 lug Drum axles. Now unless I'm mistaken everything should bolt up right? Meaning I shouldn't have any problems mateing the 91 drum stuff to the 95 rear axle? Also if anyone with a AOD car and 3.73s would like to comment how they like them and if there was a noticeable differance that'd be cool.
