I haven't been happy with the durability of the black paint I put on top of the glareshield – it's not as bulletproof as I'd hoped, and I was starting to worry about seeing scratches up there from the usual wear of having sunglasses, headsets, and so forth set on top of it. Repainting the glareshield underneath the windscreen would be a real bummer down the road, so I decided I wanted some kind of separate glareshield cover piece.
I laid out a posterboard pattern whose forward edge was about 1/2" aft of the inside of the glareshield. I made it as wide as possible without making it impossible to install and remove around the roll bar.
From this pattern I cut up a piece of 0.020" aluminum I happened to have laying around:
I made holes for the defrost fans, and cut a slot in the middle to allow it to be slid into place around the rollbar center brace:
The aft edge is captured by the same screws that secure the glareshield edge trim piece:
I took the aluminum sheet down to Classic Aero to have them cover it with the same flame-resistant, UV-resistant faux-leather stuff they use for the edge trim piece. Fast forward a few weeks, and here's the finished result. Those guys do such great work.
The upholstered material over the center slot has a relief for the rollbar center brace, and a narrow slit forward of there. Once you wiggle it into place, the seam virtually disappears. The whole thing looks great, and I can't wait to install it… just need to get that pesky windscreen finally installed for good first.
