Pulled the plastic windscreen off last night and riv-nutted the mounting holes for it and the glass screen.
There are a couple spots where the plexi screen holes almost coincide with the glass screen holes—so much so that I could not fit the thick-draw 6-32 rivet nuts that close together.
Fortunately, I made allowances for this, and bought a whole big pile of other 6-32 riv-nuts made to fit in thin aluminum. Turns out the barrles of these are way smaller. After grinding a little on the flanges and squeezing them ever so gently in the holes...
...I got them Siamesed in place so they should hold. They can't spin against each other!
Popped the Speedster windshield base on and thinking it should be a snap to make these interchangeable—except for the little problem of caulking the bottom of the glass rig to keep actual rain out. Maybe wax all surfaces generously first so the caulk will peel away easy at changeover time?
Moving right along. I plan to install the tonneau Tenax studs while all screens are absent. I'll probably install the dash grab handle as well since we're over here drillin'.
