70's Rockguard plex replacement
I picked up a used rockguard for my 72 Tradewind but have to install new plexiglass/Acrylic.
I've seen a few posts on the subject but my questions are a little more specific.
The frame measures 1/4" so I'm assuming to use a piece of 1/4" thick plex, BUT, as per the attached pictures, where the vertical support rails are fastened to the frame, the rivets protrude into the track. The gap between edge of rivet and side of frame is 3/16". 3/16" thick plex seems to thin and I would think would rattle in the frame.
My thought was to use 1/4" plex and just mark and notch around the rivets. Thoughts?
Also, after installing the plex, I was thinking of running a bead of caulk on the backside all the way around the edge where the frame and plex meet...thinking this would keep the plex pushed forward.
Any pics of your rockguard or comments would be greatly appreciated.
Sorry about the pics, still having problems with orientaion
