Capri D windows

I will be removing the D windows from my Capri in the next couple of days however they are glued in.
Are they normally glued in or are they supposed to have a rubber seal? Although the glass looks too large to fit in the aperture with a seal. 

yep, and when you refit them, make sure you put a damn good thick bead of black sika, otherwise you end up having a gap between the window and chrome trim, and have to take it out and redo it.
 
Don't ask me how I know.
