Right now I am trying to figure out what exactly I want in a roll cage i am going to put together, but I am kind of stuck on this part. I'm talking about the bar that goes from each B(?) pillar (the ones behind the front seats) for the shoulder harnesses of four points to connect to. What I want is one that is removable, maybe like, just a square tube that slides into another that has been welded to the cage, and then bolts to hold it there. Thoughts?
