I picked up a Gentex 177 mirror for the '85 Suburban and can someone give me a measurement on where to glue the mount? Mine doesn't have any glue or other old mark that I can find to go off of. Thanks for the help?

---it threatened to bust the glass when I attempted to pry them back off,so I had to get another mounting tab from a junkyard and glue it on top of the one mounted wrong...and the next 90 degree day,I found the mirror lying on the carpet--of course the other tab was still holding firm!..it's best to build a cage that goes across the windowhope it holds for you.. i have the worst luck with em...

gluing them on with silicone (ultra grey) has been working quite well for me. clean both sides with brake clean, and a little silicone on both parts to make sure it sticks to both good.
ultra grey dries pretty stiff compared to most siliconesomeone else told me that.. to be honest, it seemed weird to me, being that stuff dries so flexible.. but that may be helping it I guess...

That’s an awful lot to hold a rear view mirror on.i've never used the gray, but I have used 55 gallon drums of ultra black..![]()
