window regulator reinstall

[Peen]

I am about to reinstall my window regulators. If I remember correctly, the nylon washers should go on each stud on the outside of the slide tract next to the round retainer clip. It only had one very thin nylon washer on it when I got the truck and it's beyond re-using. The only replacement washers I could find are about twice as thick as the original. Is there supposed to be a washer on each side of the tract or just one on the outside ( next to the door skin ). Can't find any pictures of a complete assembly. Any help appreciated. Thanks. Steve.
