91-93 use a torx, and the 94-96 have a spring clip in the mirror.
I have an auto dim and a compass mirror with torx screws.That is partially correct. The standard manual mirror w/o lightsuses a Torx screw. The factory auto-dimming mirror, along with the auto-dim+compass and autodim+compass+temp has the spring clip style. - Peter
The compass mirrors I have did not necessarily come out of OCCs, I got them in a JY from an assortment of cars. All of the compass mirrors I have seen for the B-body cars, so far, have the torx screw. They all have a single 4 pin connector. I also have a auto dim from a 96 that has the spring clip, and a single inline connector that plugs directly into the mirror. The auto dim mirrors with the torx screws have two connectors, and 4 pin, and a single pin.Yeah, but yours are 1991 & 1992 Olds CCs. I pulled a compass mirror out of a 1992 Caprice to use in my 84 Monte SS in the yard a couple of weeks ago that was a torx screw mount.
look up your nearest autozone.. they have a kit for about 7 bucks or less.. use wipe the service with the wet nap thats included ... peel all old glue from the base that the mirror slides onto... ad the new glue.. then only put the base back up on the window without the entire mirror on it... (to much weight while trying to glue back in place) then let it sit for i say over night.. then next day slide your mirror back on the base.. u good to go.. i just did it a week ago..thanksAny body have the problem of there rear view mirrior flling off? Whats the best glue to use to mke sure this doesnt happen again?
