Hi this is funny because i have been working on this same exact thing on my super bee .
I have been trying to get the same info on this too .
nobody seams to have much to say about this so i have had to figure it out myself .
Just take a small drill bit and drill out the crimped side of the rivets , and use a 1/8 bit , be care full only drill the crimp off and don't damage the stainless .
Then take a roll punch and knock out the rivet half way you will have to take a pair of side cutters and snip the end off the rivet to get it out the other side because it might be slightly puched up on the end and won't slide through the other side hole .
Then the glass will slide out of the channel like a front window on a vent channel.
The seal is the same as the vent channel slide and felt plastic thing.
To reassemble that is where you need to decide what your skill level is , because it will be hard to duplicate a tube rivet (and expensive to by the tools )to buck a new tube rivet .
so for me i am using small 1/8 aluminum pop rivets 4 of them to re secure the channel to the frame .
because the original is hard to find and expensive .
Good luck . Cj
pm me if you have any other questions , most people seem to think that this is some secret or sommthing .
