A buddy is going to weld in the full US Cartool stiffening kit into a 71 Demon. He wants to put it on a rotisserie to do it so the the welds will go in better. Plus it's easier than laying on your back.
I thought that I had read the it's best to have the car on all fours to weld in the frame connectors.
Any opinions?

decades ago a local guy had em done & he said the guy jacked the car up in the middle of the stiffeners then finished welding em in (that is all I remember (fwiw). Not my area at all but off the top of my head I would want it completely loaded & up on all fours then weld em. EDIT he said he "slightly" jacked em up in the middle of their length then finish welded.

I X braced my door jams & X braced the inside of the car from side to side also before I put it up on my rotisserie. I was going for the sleeper look so I hid my frame connectors inside the rocker panels.

We installed the ones on Dads 72 Duster using the stock suspension and the car setting up in the air with all of the weight on the suspension. I left the wheels and tires on the car and used eight wheels 4 14" and 4 15"...It might look like he!! but it was very stable and worked out well... If you get it up high enough it isn't a bad job at all...The doors on his car close just like they did in 72 and never needed adjusted. I'd install them again this way if I have to... As mentioned above it does help to have something a little heavy to set in on the floor pan and help close the gap to the frame connectors when welding to the floor pan...Mine fit very well once mocked up... Maybe next time I can use the 4 post lift...
...FAFO...
