You will simply have to try all the second hand parts places around. They do not reproduce them. Yes, they are rare, so finding one may be tough as it would have to be a firebird equipped with one as I believe the camaro console was different around the map pocket area.
There are several to try.
Second Generation Pontiac Parts
Lady TATA's house of parts
Second Gen Graveyard
Franks Pontiac Parks
there are even more to list, those are just some that come to mind. They probably won't have any to be honest so you may have to simply just ask around.
