1990 GMC 1500 rearend swap

Is there any rearends other then the weak gm 10 bolt that will bolt up to a 90' gmc 1500? Would a ford 8 or 9" work? or can I convert the coil-over rearend from a 1993-1997 firebird or camaro to leaf spring?

93-97 Fbird/Camaro rears are weak 7.5"/7.625" 10bolts. A 12-bolt or 9" would be better. You would need to swap all the brackets from your original rear.

Curious as to why you classify them as weak 12 bolt has a smaller diameter pinion.I think 9"would be stronger,but why do you need?I know of racers running 10's with 10-bolts.I just say this to emphasize their strength.

The 8.5" 10-Bolt is very strong stock. Except the GovLock diff. I wouldn't waste $$ on a 7.5"/7.625" 10-Bolt. Sure you can make them stronger with aftermarket Posi, Girdle & Axles. The 7.5" & 8.2" 10Bolts are weak. IMO.
8.5"Car & Truck, & 8.875"/12Bolt Car have the same 1.625" pinion dia. 30spl.
7.5" has 1.438 Pinion dia. 27spl.
8.875" 12Bolt Truck has 1.438" pinion dia.
8.2" 10Bolt has 1.438 27spl.
9" Ford has 1.313" pinion dia. 28spl./31spl.
