If you try straightening it off the car you'll have a job keeping the two ends parallel, even if by a miracle you suddenly had a press and could push it back straight.I think it’s still structurally sound, just a little ugly. I’m not 100% sure of a replacement as the ones I’ve seen listed that look right are mostly labelled as for TD5. I may try straightening it but I think it’ll be tricky
TBH, I'd put it back on and stop worrying about it, or you'll end up having to cut it, put it back on and then weld plates onto it.
Etc, etc ,etc yuck, fuck, sh!t didnt want to do that!
It ain't really bust so don't fix it!
