Hi guys, I’m new here in the forum. I hope this is the right topic. It’s about the following: I have a Pontiac Firebird Bj. 1989 (3rd gene). The vehicle has a license plate cut-out of 34cm width at the rear. I was on the vehicle authority for re-registration. There I got a license plate for the rear with the size 320x200mm (the vehicle authority did not let me talk about smaller license plate). However, I can’t find a holder for the back of the vehicle online. If yes, where can I buy them? I have seen mounts for 340x200mm, would they fit? So the license plate holds with it and fits it into the recess on the vehicle? In the worst case I can screw the license plate directly to the rear bumper again, but I wanted to make it “ordinary”. Thank you very much for your help! Greeting, Dr. Piti
