After replacing two of the slats with spares, I sanded and coated the wood with Helmsman Spar Urethane to keep the UV rays at bay.
I didn't sand all the way down to remove all of the weathering. I suppose I'm trying to keep in the well-worn patina theme in which the 1600 comfortably sits.
I also came up with a hardware solution to drop the roof rack a few inches that required griding down the aluminum brackets.
So, after several coats with sanding in between, it all went back together.
Also, I replaced the set screw (bolt) in the shifter with a small, headless set screw.
Now all I need to do is install air conditioning and build a console so I can tidy up all of those wires!
