That is pretty interesting. It looks like they re-topped the factory towers, and did so poorly. But notice how the factory metal is also tearing. Probably because they cut into it a little bit, like a tear here tab. Then when their welds failed, it put too much stress on the factory metal tearing it. The work done is also just plain ugly. I mean my fab work is not exactly beautiful but that looks no where near professional. I wish you the best of luck in getting that resolved.
