Obtaining a Roll bar/cage on 2007 Toyota FJ Cruiser

Has Anyone fouund a roll bar/cage which does not involve welding in the passenger compartment? I lived with my CJ which was really messed up by spatter burn for years!

installing a roll bar requires welding for installation. bolting the barr allows for failure of the bolts in a roll over. it makes the job right.
why dont you want it welded??
