.........and now you don't.
Don't try this at home with a stock chassis. I only did this Hannibal Lecter surgery because of the frame connectors (Wish I knew of Chrome Moly frame connectors back then) and 12 point roll bar that together strengthen and stiffen the chassis more than stock.
On a stock unmolested chassis, these rocker panel bridges are very integral to the chassis strength. This only saved 1 Lb between both sides.
