I need to remove the fiberglass panels on my 91 GL to get at the rust.

Last time I tried this - on a '90 GL - the little screws on the
plastic hangers that hold the panels to the body were so rusted that
I ended up destroying the hangers to get the panels off. I was
junking that van so I never had to deal with getting them re-hung:
can you get replacement hangers, or do folks jury-rig it some other way?

Steve, 91 Vanaru GL in Chicago where they use LOTS of salt.
