TX '64 Under Way

[knomadd]

I've never worked on a 64 pickup, but of the other GM vehicles I've worked on from the 50's to the 70's, the door glass is attached to the regulator so it will need to either be removed or held in place somehow. I'd recommend taking the window out if you're going to have it apart for more than a few hours. You wouldn't want the window to fall inside your door and shatter.

As for the vent window, if you leave the door glass in, the vent window won't need to come out. If you take the door glass out, sometimes you can get it out with just loosening the vent glass, sometimes you have to take it out. It's only because the door glass uses the vent glass for the front run channel that you might need to take the vent glass out.
