Looks like the part is called an Up-stop bolts to the regulator.

BTW. Adjusting windows is a PITA. More so on a convertible.

also I think this is a great video but is for HT cars

There is a stop bracket. It is at the back portion of the regulator frame. It should have a black rubber/vinyl tip on it.

Thanks for the replays great help I did get windows adjusted. Found that when I changed height I also had to adjust front to back. Window did not close far enough forward or was to close After several attempts I finally got it. Thanks again
