On my '48 half-ton, I just installed new channels, and the glass is new, also. Everything looks okay, but the window won't fit down into the channel. I tipped it in to the door like the book says, but when I try to pull the top up to set everything level, it jams. I tried grinding off the lower corners of the glass frame a bit to make it easier, but no luck.
Anybody got any tips or useful suggestions? It's really frustrating. I'm sooo close to being finished.
