There are a lot of parts that are unique to a Suburban. Clamshells are hard to find and even in poor shape the parts that are attached are good to get: glass,holders, interior and exterior handles, upper and lower hinges etc. The rear interior trim is always a good catch if you can get them, they rust because of leaves and debris sitting in the channel for a long period of time. If it has the rear seats (more common with clamshells)they are worth saving, rear fenders etc. Another piece that is worth saving is the step-up piece that attaches the floor to the rear doors (the bottom of the doors and the bumper valence attach to it) The real question is space, time and storage. A clean title and tag are always wanted. My two cents! grin
