i want to put a forth generation firebird center consle in my third gen T/A, is it possible, and if so do i need to fabricate anything? and what would i do with my electronics, i.e. power mirriors.

 

Yes it's possible and it's been done many many times, if you'll use the search function to search the boards you'll find many posts about it, what needs to be modified, how it fits, and pictures after the installation. You'll probably find guides for installing 4th gen door panels, dashes, gauge clusters, etc. Tons of useful information can be dug up with the search function.
