I have been attempting to fix a issue with a Mercedes Benz 300SEL mod that im trying to kinda restore and fix fully, and up until now, my progress has been pretty good. However, there is this issue that I'm struggling to fix. I've recorded a video to provide a clearer explanation of the problem. Could someone please watch the video and offer guidance on fixing this issue because i'm relatively new to this.. And also theres another issue which i didnt get to record because its random , the issue is that the front bumper right side gets randomly damaged (not fully)
