Yeah either 4.10, 4.57(i think) and 3.90 are the only gears i've ever been able to find for these. There are some parts available for these thigns but not very many. the 14 bolt swap is common because of availability i think yes. I found 3.90 gears (in search of lower rpms) but new the set was like 260 and i have 4.10 now so not much of a gain for the money. They dont die if you keep em lubed. I heard about some fiberglass hemi that kept ruining any rear end it had, they swapped that 10bolt in there and been running it ever since. The reading was it broke BUILT dana 60s and about anything else out there cuz the car was so light and had so much power transfer to the rear. It'd snap a rear end after one run supposedly. They said since they put that ho72 in it's been running 6 years with no problems at tons of drag events. Could all be a bunch of hooey but hey makes a good story...
ok i'm done rambling now...
