I noticed when I unbolted my regulator from the door inner frame that two different size bolts are used: one M6-8 and two M6-12.

Does anyone know which one goes in which position? RealOem only shows that both lengths are being used without showing which one goes where...

Thank you.

And the answer is… Yes, the front most bolt needs to be a short one. As suggested by HB Chris, if you poke a screwdriver through it, you hit the mechanism behind. So the front one is 8 mm. The two rear ones can be 10 or 12.
