I pulled the luggage rack off my '85 and found six old wasp nests
underneath.  Those drain holes are wasp magnets!  This van lived in eastern
Oregon before e I got it where it's warm, and wasps are prevalent.  It's
easy to remove the luggage rack and clean out all the crap that gets
underneath, and I think this should be done every few years.  Of course
you'll need to replace the bolts with stainless steel bolts while you are at
it!
