I'm doing mine today
Our H34, Epitome', is a '86. As such, it has no inner frame that needs replacing. All four windows have teak trim inside. The old windows ALL came off in one piece. I had new blanks cut slightly oversize (just in case) and will bevel them on my table saw to match the factory units. Then they will be lined up with the old ones for drilling of the screw holes. (don't want to goof there) The new plastic is lexan and is the same thickness as the old, 1/4". RTV is the way to go for the gasket. Just be sure to tape it off. I'm hopping they will look as good as Rons'. My Beckson `Rain Drain' ports are so clear, they look open. Hum, better get some curtains.
