I already did it because when we purchased the truck it came with what I believe is an OEM later model roll bar that was not mounted and taking up space. I installed it and extended the mounting brackets for the long jump seats. I had to fashion some "L" type of brackets to support the outer bumpers. I'm confident that the entire install is not up to your standards but it works.
Are you planning to put a rollbar in your truck?
I agree. It is on my "things-to-do" list. The biggest problem that I have is sourcing some stout angle iron of the proper dimensions. Unfortunately, I don't have a fab. shop.I’m glad you posted that pic.
I would use some stouter angle iron for those supports. If you can grab those and bend them with a pair of pliers, chances are they won’t hold the weight of a person.
