Hello Circlework,
If you don't mind doing a little bit of work, a weekend project with a hydraulic bottle jack, or portapower unit would assist you straighten this unit.
RH door top off my Perentie which had been rolled when I got it off Grays-Online Auctions, obviously the Roll Bars did what they were fitted to do.
I have enclosed some photos to illustrate the extent of the damage, in my opinion it is repairable / straightenable, If you agree and want it pm me
your address and you pay the postage.
Cheers.
