After some testing and such I decided the panels that the upper latches are bolted to need stiffeners. The 14 guage sheet metal allows fair amount of flex and that can't be good. So I cut some light angle iron pieces and tacked them down in addition to running the latch bolts through them. See photo. Now if the paint will ever dry I will get them installed back in the WMB.
Now that the rains have returned I noticed that the bottom of the door panels were wet. (Photo #2) So out into the rain I went and pulled them off and I discovered two things.
One is that the PO secured the fabric with duct tape and that blocked the drain holes behind the door panels. So I removed most of the old tape in hopes of getting the water to drain.
And two is the water appears to be coming in the half circle cutout under the wing window. (Photo #3) So I covered those holes from the inside with some weather sealing tape. Hopefully this will stop the fabric from getting wet in the future.
The other thing I discovered was that my window regulator screws were loose and falling out. That's one less rattle to annoy me tomorrow.
