My original interior rear view mirror fell off. While scraping off the old factory glue from the windshield to put it back on, I noticed it was originally placed slightly (maybe an inch or so at the most) closer to the driver's side. Shouldn't the mirror be dead-centered on the windshield left-to-right? I just want to make sure I'm not wrong in assuming the factory worker just had an off day when I put mine back on right in the center left-to-right. This was the original mirror and windshield.
Probably a stupid question, but remember: There are no such things as stupid questions, just stupid people.
This was the #1 search result for me and had no answer! My mirror also fell off, and I got to thinking about an official placement after noticing it wasn't glued in line with the t-top center rail. Turns out, the 1989 Camaro FSM will tell you exactly where to put it.
Followup after doing the job: instructions are good. 689mm from the bottom of the windshield is a nice placement, high enough that the mount is fully in the shaded blue part of the windshield so it's harder to see. I wish I would have painted the back side of the mirror mount black, mine had some cast metal areas and they are more visible through the outside of the glass. I also measured slightly differently:
I used the t-top support rail to make a centered column to place the metal button between, and then boxed out where the bottom of the mount sits with another piece of tape. This makes it very easy to align and install on the car, where you're kinda looking at it at an odd angle. I ended up being 1-2mm off dead center, but it's virtually imperceptible.
Few folks read the fine print ... but these mirror button adhesives can only be put on in temps between 50 and 70. One night after dark, I glued mine - it was 72 according to my local weather app. It seemed to glue fine, and I let it sit overnight. Next day, about 10am, it fell off again - I had not even put the mirror on yet! So - wait for cooler temps.
Also, you can't paint the mirror button, it will not stick no matter what the temps if it's not 100% clean bare metal. Many folks also fail to scrape ALL the old glue off the button as well, and that will lead to failure. Button must be smooth, flat, and clean of any contaminants, and the glass must be scraped clean of old glue, and those surfaces both prepped with the little towelette to have any chance of success.

Agreed, I think it was in the mid to high 50's on the day I did this job and it is still holding strong.

For sure, I was talking about painting on the back side of the mount that is attached to the mirror itself. After cleaning off the old glue on the button, I did a very light crosshatch diagonal scuff with 320grit sandpaper and then cleaned it again with rubbing alcohol before using the supplied activator pad thing. I believe that was suggested on the glue package.
