Omega B – Z22XE – completely replace or repair crossbars?

Hello dear community, I was now at the TÜV, which still a few defects come to me was aware, however I wanted to have an opinion about the detected defects in the red bordered area on the picture. I have already seen that there are repererature sets for the crossbars for the crossbars, but I would also need special tools or a self-made tool. Now I also have the possibility to get both crossbars completely new for a very good price. The crossbars are from the company “Monroe”, I mean to have read that which are probably relatively usable, jmd. Experiences? LG
