Frame connectors on a rotisserie car?

I did it on a rotisserie with no problems I welded them when the car was on its side and took lots of measurments to be sure it was straight, flipped it 180 and did the other!! It was a little scary but it turned out great!

Thats what I was thinking!If its on its side!!Im leaning that way myself,was hoping to hear someone who has tried it.Thanks for the reply.
