im having a cage put in my 74 this month. i was thinking of attaching the front hoop to the floor, but i looked underneath and it looks like theres a hollow section under the floor. this concerns me cause i wplanned on bolting some plates to the underside of the cage mounts(the plates the tubing is welded to. BUT, the sloped portion of the floorpan(where the hii beam switch is) appears to be safe of obstructions, so my question is what would be stronger? id like to be able to use my p- brake still too. does anyone have close ups of their cages?
