figured it out. Working great both up and down, now I just need to get the key cylinder operation working. Do your tailgates use the same key as the ignition? Mine doesn't seem to fit properly, but there was no secondary key when I purchased the rig.
The door key on mine operates the rear window and the gas fill door. The ignition key is separate and only operates the ignition.
Note that my two roller channels are original but I bent up a custom u-channel that holds the glass and then welded the pins and connectors. As you can see from the picture my skills are a bit lacking but it works. My original u-channel literally rusted into tiny pieces.
I know the pain. The more I worked on my rear window the worse I seemed to make it. I finally got it to work again but somehow messed up the tailgate key switch so it no longer works...only the dash does. I also removed all the weather stripping in frustration due to the binding preventing the window going up or down smoothly. So when I say working well that is relative since the glass is against straight metal at this point. But it does go up and down...I made it worse.
This thing is really pissing me off. I hate a damn 55 rear window
