1970 Duster Quarter Glass

First off let me say I did not take this car apart and it is my first ever Mopar Project! my questions are, is there a piece of rubber weather strip that goes on the front of the quarter glass in the channel, that I have shown in the picture I sent, and if so what is it called? also do you remove quarter glass from frame to install or does is slide in as one unit and I assume that the roof rail weather strip goes in first, then you slide in the quarter glass? some pictures of assembly would be nice! and my last question for now is, what is the procedure of installing the roof rail weather strip?
