s13 glass

hello, names brian.
i am in the process of gutting an 89 240sx for a project circle track car and i am looking for some hints, direction, pics or any other help getting some of the glass out without breaking it.
the door glass was no problem, but i don’t know how to get the 3/4 glass out.
and the hatch glass.

any help would be greatly appreciated.

thanks,
.brian.
