Cam,

Absolutely beautiful work on your '60 Amazon S, however, I'm almost certain that hfav is talking about the "rotating window" or vent window, and the vertical channel runners, one of which goes into the backside of the rotating vent window's long, long leg, which also serves as the regular window's vertical guide, with a fuzz-lined inner channel.

hfav,

I'm getting ready to do the same replacement of the rotating window's rubber seals.

Yes, you should remove the door panel (be careful, get right under the metal clips, they can be rusted in place and tricky to remove smoothly, without damaging the door's 30+ yr old side-panel backing material)

While you place the rubber seal and fuzzy window channel guides, it will pay off big time in the satisfaction you get if you also do the cleaning, lubricating and adjusting of the other parts, while you're in there.

Handle and lock mechanisms, window crank mechanisms, cleaning the bottom of the doors' drainage areas, adjusting the crank cable pulleys for smooth window crank operation, side mirror mounting and "mirror position spring tension" adjustment, if you have that type of side mirror. All good things to do

You just have to mentally commit. It ends up being fun, educational, and the right way to do it, all rolled in one.
