Swinger Tight Window Issue

In my 70 Swinger I just replaced my drivers vent frame, vent glass weatherstrip along with the glass channel weatherstrip as well, and wow, is that glass tight in there now. I mean holy crap tight, so tight it was hard to push up into the frame before installing the vent frame, and so holy s**** tight I think I may snap the regulator if I should try to roll it up or down by the window crank.
Has anyone else ran into this?? Im pretty sure I did everything correctly, would some white grease in the window channel help any?
Im seriously afraid ill break the regulator if I try to roll it up or down, Ive had to push up or down on the glass while turning the handle, and it will only go so far.
Any help would be greatly appreciated.
