That is the same thing I was recently made aware of. It leads me to a question on my mirror attachment.
Years ago when I restored my 914, I used the typical car store 2 part mirror adhesive and it would hold for about 10 years and then drop off, and I would then reinstall with the same product. I think I last did this adhesive install about 3 years ago, but then soon after, was made aware that the adhesive patch is the better method. I purchased the patch and was hoping I could slice the current adhesive bond with some thin SS fishing line, but no luck. Does anyone know of a good method to remove a mount that was attached with the liquid adhesive? Or do I just need to wait another 5 years for it to weaken and fall off?

Take an adjustable wrench and once you get a grip on the mount, twist it sideways to break the bond. Don't try to pull it to you, away from the glass or you may break the windshield.

@dr914 @autoatlanta.com. Thanks George, I didn’t know there was a factory part. Is it a kit, or do you have to get adhesive too?
It's just double sided sticky tape wit a thin foam core. 3M makes it.

Heat gun but not too hot worked for me.
How many inches down from the top and what reference point. I think I remember George saying 4 inches down from the top of the trim to the top of the stock square pad, but I can no longer find the reference. Mine is definitely too high.

Looks like 4 inches is correct. From the service manual:
