Update: After a google search for picks of the regulator I decided the fan shaped gear must be held on by a large rivet style fastener. With my one arm jammed into the door as far as I could . I slipped the gear in behind the handle with the small drive gear. At the other end of the fan shaped gear a hole lined up with another on the regulator frame. I decided to insert a bolt and nut to hold the fan shaped gear in place . A little tinkering to find the exact location in relation to the handle crank and it all tightened up nicely. I lubed all slide points and the window works like factory new. I’ve taken other windows apart before and let me tell you . If you can find a way to fix what you have without taking it apart or out of the door you will be in a much better mood when the job is done. Hope this helps someone at some point. Have a great day building your trucks.
