Regulator Window Mount

Hey guys, first post on here, I'm planning on making a full introductory post with my truck but for now I need a bit of quick help. I replaced the passenger side regulator on my 2001 Prerunner and as I was removing the old one I noticed that the actual mounts that are glued to the window had come off and were still bolted to the regulator frame. Wish I had taken pics, hopefully I'm explaining myself clearly...

Has anybody had to deal with this before? I slid both mounts back onto the window and they were fairly tight but when I went to move the window up and down a few times they dislodged again. I want to just fill the mounts with some sort of glue or epoxy and then slide the window back in and let it dry, just curious if someone had a better solution.

PS Since everybody loves pictures, here's the truck in question.



Soon to see new wheels, tires, 5100's and Eibachs all around...

Thanks!

Tyler
