Bill,
Keep your stock glass and place two bolts through the upper beam support with fuel hose on the bolts (or heat shrink) When transporting the car (hopefully to Sebring PCA event..lol) and slide the glass down into the door resting on the two bolts. If you have a factory hardtop, push on the top of the glass to shut the door. This will make the glass go under/into the rubber like it was rolling up into it.
I'll *try* to get some pics of a door and some glass today
