Dear mysteriousspook-- The answer is yes, you can use body parts from another vehicle on your 1992 Mazda pickup. I will need a question with more detail before I can give you a specific answer. Get back to me if you can. Good luck from Bovan.
Mazda and Ford are the same trucks...find one the same year and everything should bolt right on.
