Omega B – Bump in the tailgate

Hello forum! Unfortunately last night I was forced to park the fighter bus on the road, as the garage yard was completely parked. It came as it had to come, a very unbeautiful bump now adorns the tailgate. Of course no name was added. The hit was probably almost point-shaped slightly above the license plate. It is about 2 cm deep, so in itself annoying, but not really tragic. However, the tailgate does not open any more, seems to be warped / tense. My plan is to weld up a nut, put on a threaded rod and pull out the bump over a fixed counterpart. I hope it’s a frog and I don’t need a new flap. Anyway, the flap has to open because I have to hit the shock absorbers. Does anyone have a better idea? Pictures will come tomorrow…
