Just kidding about the facts and logic, Bob. And like I said, I don't fit into the car to do the welding so I leave it up to the welder to do his thing; I think he finally bought the small torch that you mentioned. A few years ago I did a Mustang for a friend, and I hole-sawed holes under the floor plates. We fit the floor plates, loop, back bars, halo, and front down bars, then slid the floor plates out to drop the cage to weld. After the cage was welded we slid the floor plates back in, welded the tubes and floor, and braced the bottom of the floor to the rocker boxes. Came out really sweet. It wasn't as much work as it might sound, and it really got the halo tucked up into the roof.
