Someone check my logic here

In the last month, I've aquired two different rear ends for the low, low price of "Come get it and it's yours..." Gotta love free parts!

One is out of about a 94 Camaro, the other is from an 89 Cadillac. The Camaro rear is too wide for my 57, but the Cadillac one is an exact match to the stock width. However, the Cadillac rear is a 2.93 while the Camaro is a 3.42.

Both of them are 7.5" GM 10-bolt open diffs. Not the greatest in the world, but again, they were free and should work just fine for me. 2.93 isn't horrible, but I'd much rather have the 3.42.

Is there anything that could stop me from swapping the ring and pinion from one to the other?

should work in either or... I would do a rebuild with new bearings and seals and a c-clip eliminator also while you got them apart...

swapping the r&p requires special tools. pull the cover and check it out before investing too much time and effort only to find a problem costing $$$.

I already planned to replace all the seals and bearings. No point in not doing it while I was in there anyway.

As far as I can tell it requires a shop press, a torque wrench and a dial indicator, unless I'm missing something. I got that covered.
