All of the tube I bond to the body for mounting purposes, will be welded to a tap pad. A tap pad consists of 3 pieces of flat stock steel. I will make the top pad 1/4" thick with clearance holes drilled in them for the bolt to pass through. The bottom pad will be 1/2" thick with threaded / tapped holes, so the top pad will bolt to the bottom pad. Weld your tube or pipe to the top pad. Position your tap pads, and body mounting tubes, so you may unbolt and lift off the body vertically. Mounting your body like this, will allow the body to be lifted off the chassis, with out disturbing the bonding adhesive attaching the body. You may even want to put a 1/8" or 1/4" clearance drilled spacer in between the top pad, and threaded, tapped bottom pad. This will give you additional clearance from left to right, when you unbolt the body and remove spacer and lift off body.
