2wd rear end swaps

Have 1977 c 10 short bed fleet side street truck. Anyone know what other rearends will fit unser the truck that are narrorer. Don't care about the mods to do it just what i am looking for. thnx

Something from a Corvette, Camaro, even an S-10

I would say any year 10 bolt, even a newer one with discs just make sure you have 16" or larger wheels to clear the calipers and you'll need to fab a parking brake cable. Otherwise just look for a 10 bolt axle the are all very similiar.
