Last night I had about a half an hour to myself, so I went out to the garage and shot the drivers’ door mechanism with some white lithium grease to see if it would help smooth things out. Overall, it is much better, but there still seems to be someplace internally where it’s catching—it could be the lever arm getting caught on the inside of the door somewhere. I’m going to break the passenger door down this weekend (hopefully) and replace that regulator with the one I cleaned up this past winter.
I also started replacing the bolts fastening the rollbar to the body. The PO used some kind of zinc-plated hardware, so I bought a handful of grade-8 replacements and started swapping things out. I also found an angle bracket in the decking section of the Home Depot that I think I can modify to use as a secondary tiedown for the bikini top straps. (There’s one tiedown fastened to a passenger-side rollbar bolt, but the driver’s side has nothing).
Still on deck: A rebuild kit for the ThermoQuad. Stay tuned.
