well since nobody came up with a brilliant idea for me I figured one out which seems to work pretty well.

Here's the wing glass & frame with the original rubber pulled out...



here's where I used an inner tube from as mountain bike I have to replace the rubber under the glass, I had to double it up but if fits quite snug now & wont go anywhere, this worked amazingly well. After fitting the glass into the base just knife off the excess rubber w/an Exacto or razor blade.
