comaptible parts between '85 and '90 tercel?

I'm cutting my old '84 trecel (automatic) lose after lost interest/lack of $$ in repairing it. so before I sent it off to the junk yard, what parts can work in my '90 trecel (carb/manual)? I don't mean nuts and bolts, big stuff like alternator, A/C system, etc... sorry if this is a dumb thread, I just don't want to have to replace a part later which I could have had for free. thank you!

as far as i know parts only exchange between 86-90 tercels, 85's and back are a totally different engine and such, only reason i know about the 86-90's is because i have an 88 engine in a 90 tercel.
