8. The interior rollcage is far from complete, but it's coming together nicely. The halo was constructed first, and then it was fully welded and painted. The A-, B-, and C-pillars were welded to the 3/16-inch rocker plate, which is supported and welded to the frame by 2-inch-square tubing. In the rear of the cage, the center supports were welded directly to the frame.
