I bet his rollcage is made out of schedule 40 pipe with pipe elbows welded on instead of bends. Probably got a Supercharger made from a Shop Vac, ratchet strap seat belts and shifter handles from the door knob aisle.
That reminds me of some crap I saw last year at a local UROC event. Two good ole boys rolled up in a Scrambler with some home made half doors that locked using a privacy fence lock. You know the ones that have a metal bar on the gate and the post has pivoting hook that latches it. Then you just lift up on the tab to open it. Yeah one of those. The latch was welded to the side of the body and stuck out like 4 inches. I laughed my arse off.
