I assume you are suggesting swapping a 4.3 liter Vortec engine into a '91 Sonoma that has a 4.3 liter engine. I believe this would be a major project. The '91 4.3 liter has a TBI fuel injection system and the Vortec uses a different, higher pressure system with injectors at each cylinder. I think you would need to change the fuel pump in the fuel tank, computer, harnesses etc. The Vortec also uses a mass air flow sensor so the air induction system would also need to be changed. Not compleley sure on all the changes necessary but I do believe it would be complicated. I just finished swapping a '90 4.3 into a '94 Sonoma. Both are TBI injected. One thing to watch -- the OIL PAN. The oil pan on the four wheel dirve version has a shorter, deeper sump to fit around the front drive axle. The 4WD version will probably work on a 2WD but I would check it out. Good Luck, Jim

Will a GMC 1996 sonoma rear end go into a GMC jimmy 1997 model?

Yes, but there's no guarantee that the ratios will match up... the Sonoma might have, say, 3.73 rears while the Jimmy has 3.42s (standard for the Blazer, Jimmy, and Bravada for that model year)... you'll have to look at the RPO codes in the glove box to determine this... 3.42 rears will have a GU6 RPO code.
