One other thing. I didn’t mention earlier because it was a problem with my 1978 Newell and I thought would not apply here. We ended up trimming material off of the aluminum opening for that very reason. The glass would not set in the opening properly. It would set proud of the opening. I think the glass needs to be on the same plane as the surrounding body. Measure the glass and opening carefullly.
I should stress that in both cases the coach did not move an inch for 24 hrs once the glass was in.
