I have a van without rear-view mirror and I bought something to attach to the rear-view mirror bracket on the windscreen. The attachment system looks like this:
The three small hooks are supposed to grab around the metal bracket on the windscreen.
However, I have tried attaching it pretty hard and it won't go. I'm afraid of pushing against the glass even harder.
How would a professional do this? Do they support the windscreen from the other side when attaching something like this, or is it safe to just push as hard as needed?
