87-92 Camaro/Firebird convertible trunk lid.  These are very often badly damaged or rusted and can be very hard to find in good condition.  This lid isn’t perfect but it’s better than a lot of these you’ll find.  It has no dents or damage.  The underside does look like it could’ve had some rust repair on the underside lip at some point.  While this piece isn’t perfect, it is much better than a lot of these you’ll find and would be a good replacement for a badly damaged or rusted original.
