I was fortunate to pick up several R-Model items from a forum member including a set of the aluminum door glass frames. They didn't come with any installation documents so if anyone has installation details for these aluminum frames I would very much appreciate some help. No idea how they're attached to the doors. Couldn't find anything online.
Send me an email at gt350bp@bellsouth.net and I'll send you my notes and installation sketches. These were the most difficult part to install on my car, as I was not happy with the fit. Had to re-bend the frames for a better fit to the window opening. Took me two weekends to get the fit that I wanted without a big gap.

Craig Conoley at Paradise Wheels in San Diego made some. He may have installation instructions and/or necessary hardware.
