My 1978 fixed ports are leaking and one is cracked. I can see that the inside frame rivets have to be drilled out and that will remove the frame. But the plexyglass looks to be mounted in a recess in the cabin top from the outside. Is it just setting in the recess and held in w/ adhesive? If so, then do I need to even take out the frame on the inside? There is not a frame of any type on the outside. My thoughts are to replace the cracked one and then re bed the others. I am then going to put oversized plexyglass ports over the stock fixed ports. As in this article:

Double the plexy should keep it from leaking for many years to come. But, first I need to understand the mounting of these stock ports. Any help and thanks.
