I put in new hull weatherstripping in my 88 camaro and the window did not quite line up, not to mention hard to close. I figured I adjust the glass to match the new weatherstripping when I discovered the window up stop is broken, No one seems to make or sell new stops. I did a search and found a vendor that sold them about four years ago but not now and a member on this site that offered to 3D print them but he hasn't posted in a few years. I am hoping he answers my PM. Does anyone know of any other vendor to find these stops? Plus, how would I replace the stop? It looks like I need some kind of spanner wrench and I am hoping I do not have to remove the glass.

All the searching I did only shows the bottom window stop. I decided to check that and there was no stop. Its disintegrated! Just ordered a pair from Hawks.
