Sorry for the late reply, I was on vacation.
This setup is a temporary test to see what would work for what I need. This is the only car I will have to do this on and I don't want to spend big money on a set for a 1 time use. My neighbor is a welder and we are making a better set for it. The angle brace was just a scrap piece to hold them temporary and the u channel that is welded together is getting a 1 piece one made.

I only plan on using them to put it in the trailer, roll into the blasters shop, then back in the trailer and lastly back on the lift. Then off they come and never to be used again.
I had a rotisserie all lined up till the owner took me off the list and moved his buddy up to the top. I am now using another body guy but he has no rotisserie.

I understand what you are saying and I have tried to buy 2 used sets already but they sold really fast. There is another 1 but shipping would be crazy money. Just my luck lately.
Thanks for your input. David
