Interchanging parts is sometimes a risky business, but it can be done with experience, or if not, then with some time and attention to detail.
Try this. LMC TRucks has an online parts catalog for all older Chevy trucks. I use them for all my 88 Suburban parts. If you check it out, you can compare their part numbers between years, and it should let you know which ones have the same parts and can be swapped.
Also, look online for an interchange library. I want to say I've run across one, but it cost BIG money for access. Also, consult your local parts yard. They DO have access to that library and know which parts are generally interchangable.
Good luck!
