Help needed installing front and rear glass.

yep clips are in and all the rust has been taken care of. unfortunately I don't have a close up right now.
does the head liner have to be in? I know the dash has to be in for the front one.
I don't think there is any lock strip on these gaskets.

I think I will put the windows in do a leak test and go from there.

Any tips on headliner installation?
