b2200 b2000 body swap, or engine

alright here it is,
I have a 1990 b2200 with bad engine needs brakes but great body 160000 miles... I can get a 1987 b2000 with 51000 miles that runs great but a tree fell on it so body is totaled I can get it for $250 and want to. I need to find out if I can just swap my body onto the b2000 frame ( it is the same body extended cab) or would the engine and tranny swap out if not the body??? anyone know?? please help thanks, John

I can see no1 has replied if your still looking for an answer, I'd say that everything should work in the swap.

just swap over the engine and tranny
