need advice with differential change
I would like to get a little more power from my 1987 olds cutlass supreme 307.Before I go to a 350 I want to try new rear gears first. Maybe 3.73. Will this give me a little better acceleration and where might I find gears to fit my car. Also did the 1987 442 have 3.73 gears and would they fit my cutlass. thanks for any advice.

On the other hand, the S-10 trucks and third and fourth gen F-body cars also use the 7.5" axle. If you're looking for wrecking yard parts, you can swap the gears and even a limited slip carrier into your axle housing. Just be sure to check for the proper spline count on the axle shafts.

I just realized you are from New Jersey. That means the axle swap your looking to do with 442 / GN / or SS monte parts is pretty easy. A lot of those cars cars are getting parted around here because of rust issues. I see the axles from time to time and they are expensive (but less than the 68-72 A-body size). I guess it depends on your perspective.
