Hey Kevin drivers side with a rollbar is easy just add one of these.
For the passenger side I would carry that bar across, drill tap and helicoil into the rear frame rail. Use a bracket the same as the rear rollbar brace. Tie that forward to the extended crossbar.
I would rather see you put a rollbar on the passenger side if you are installing shoulder straps on that side. You could tell them it came with an American lefty rollbar and you added the righty.
