There are two button-head Torx bolts that go into the cast
piece behind the sail curtain. They are pivots for the scissor
frame. One backed out and ended up in the area just above
the drain tray, above the wheelhousing. I got it back, but not
the copper washer that goes with it between the cast piece
and the steel arm.

Decided to vacuum out all the oak leaves I saw while fishing
for it, and there's some decent rust starting around the drains.
Have to get after that. Both drains were full of wet crud and it
hasn't rained for weeks.
