I have an 87 Firebird and I have been looking around for new door panels. I found a pair of 82-85 Camaro vinyl door panels I would like to use. I just would like to know if I could use them in my 87 Firebird and if so would I run into any issues.

 

They will probably fit the door, but you're going to have to cut quite a few holes for all the trim and hardware.

Look around on here and eBay, you can still find decent original door panels for around $100 which will look correct, and you don't have to modify them to get them to fit.
