RHD to LHD tub conversion

[Turdworlder]

I cant find out if my roll cage or tub is bent, so decided to buy a tub, the only available for now is japanese rhd in good shape for 820$. Roll cage's weld is snapped and two sides where its connected at center with e torx are at different levels, i dont know if its the reason of sports bar being uneven. So already bought the roll bar. I want to know if i can get away with just rollbar swap, the current tub is in good shape no rusts,bondo,weld at all but because of unidentified bent the windshield at driver side doesnt seat well, cant adjust driver side sports bar. How to detect tub bent?

Could this be also the reason? The nest for windshield to tub attach bolts are not even. The bent nest side actually seats correctly and correct nest side's sports bar is unadjustable

What a drag. I typically measure diagonally across two square common points, on the same plane, that are the same on both sides, say from the upper door hinge to the rearmost hardtop mounting hole on the opposite side: measure from driver's side to opposite, and repeat on the other side. Compare the two sides and see if the measurements are the same. If they are the same, you are good on that plane. if they are not the same, double check your measurements. Same result-you are out of square (twisted or bent). You can even break it down into smaller sections-forward most hardtop mounting hole to rearmost, just make sure your sections overlap. Best is to do the entire tub at once, which may be a challenge with seats in the way. Don't measure from the windscreen frame, as it may be bent and is not part of the tub. I don't know of another way that doesn't include tub removal-perhaps someone else has a better suggestion.

Hope i found the problem. The roll bar is bent/different height. Fingers crossed that new roll bar will solve the problem. Its still on its way to me, also i guess rhd tub will have transfer case mount and boot at different side, firewall conversion would be enough for me simce i will do everyting alone at someones backyard given for time.

Good luck, and hopefully that is the problem and the new roll bar solves the issue.
