Rotisserie Build. Will it hold together?

Dang, took a while but it is built blasted and painted. I pretested it all prior to paint and welded the body mounts up while they were mounted to the body so they would be aligned correctly. So anyway it works great and at the adjustments it has the car is about 98 % balanced with a slight bias towards being upright.

I built the body mounts so that when the car is on the machine, the axis of both rotators heads are inline with each other and parallel with the floor. This makes uneven pressure on the car nil and binding nil as well.

I will tie the two rotatory stands together with a pipe which will slip inside the center leg tube of each one facing each other, running under the car lengthwise.

I used about 1/2 of a US Car Tool rotisserie kit and a fair amount of metal. Nice thing is I have a bunch of good bolts and metal left over from their kit for other projects.

The rear tires on the rear rotatory unit are fixed and pneumatic so when the system is tied together and the car is on, it will be able to be pushed and towed like a trailer or waggon. The front rotary stand unit will have a tongue like a waggon which can be pulled with a truck or a wench to drag the whole combined assembly around.
I will add a couple more pictures when I put the car back on. The paint is on thick so it dries a little slow.

Paint used is XO-Rust grey bought from True Value Hardware, applied directly over blasted steel. I did not blast the steel bare but it is all decently blasted and de-greased with lots of denatured alcohol.
