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?
