Will '76 door glass fit in '85 door?

[ben@speedbarn]

Hey guys...haven't been around here for a while. When I was rebuilding my 76 GMC I replaced the doors and bed with a set that were from an 85ish truck(not exactly sure). I saved the door glass out of the '76 doors in case I ever needed them. Well shut my drivers door yesterday and the glass shattered. I noticed online that the part numbers for the regulators and trim for the windows are different between 81/below and 82/up, but haven't found any info about the actual glass.

I've attached a picture of it almost finished just for the heck of it.

Thanks...
