1989 5 speed in 1987 chev ?

[cr92]

hey guys first post on the forum but i've been browsing for a few months now. i am currently working on a project truck its a 1987 chevy short wheel base 2wd with the 4.3 tbi in it. i have a 1979 350 here i am planning to convert to tbi.

I also have a 1989 chevy step side 4x4 short wheel base with a 305, 5 speed tranny in it.. i have been using it as a winter beater for a few years now but the chassis is rotted out and i was wondering can i use the 4x4 5 speed tranny out of it in the 2wd 87? or is this not possible due to the 4x4. the 87 is automatic and everything I've owned is standard.. just don't feel right haha!!

Thanks for looking!
