There is no just drilling a new hole. The factory point on the driver side is a large nut welded to the flange of the cab support and you have the thickness of the the cab support and the floor together at that point. A new hole would require a special heavy flanged oval washer made specifically for mounting seat belts. I design seat and belt installations as a part of my job and have for nearly 20 years. We destructively test this stuff. I've never failed a test yet so I guess I have pretty good instincts. The stuff I see done in the armature Hot Rodding community usually scares the crap out of me. Often the improvement in seat and belts is more dangerous than what the vintage vehicle came with.
