Is the glass replacement part for either side view mirror interchangeable between Camaro and Firebird? I can obviously see the mirror housing around the glass is a different shape on camaro/firebird, but is the glass plate insde each unique to each or common? Is there a single p/n for Camaro and Firebird side mirror reaplcement glass? Will the anti-glare mirror plates (blue tint) from 98-99 Firebirds work on any 4th gen Camaro?

Also, is there any difference in part number between the manual mirror glass plate and the power mirror glass plate? Any difference on the backside for attaching the ball/socket screws of a power mirror assembly or the cables on a manual mirror assembly?
