Can I swap out my 94 Chevy Silverado rear end with my 95 Chevy Camaro

It's usually best to go with what the vehicle was designed for . Have the rear end rebuilt by a pro . Don't go cheap it probably has a limited slip differential and will take some expertise

It can be done but it will not be a plug and play type of job, mounts will have to be made for springs, shocks, driveline reworked for the truck differential, ect.

The rear axle in a Camaro is narrower than your truck's rear end, so you really can't do this. Long ago, hotrodders used to switch to tougher rear ends to handle more power, but we always measured before planning a switch.
