Have a 1980 Olds Custom Cruiser. Side window dropped down so I opened things up to find why. The regulator tape, a plastic strip with holes runs up and down in a metal tract. There is a very small odd shaped piece of plastic the hooks into the hole at the end of the tape and attaches to the larger plastic clip that bolts to the bottom of the window. The small piece of plastic is broken. A lot of parts websites with Oldsmobile parts all sell the regulator tape, rollers and window motor, but so far haven't come across the tiny part that makes it all happen. I'm sure this window set up is used on other Olds cars and for other years. Any one ever have this problem? Where to find this part? Thanks, Scott
