I bought an Auto Twirler years ago from the factory in Plainfield In., don’t know if they’re made there now, though. Unpainted it was about $800, I’d guess that they are more than that now. It was easy to set up, I had to make my own adapters but that wasn’t a big deal, I just bolted it to where the bumper brackets bolt to. Easy to get the body centered, easy to roll around the shop. I never used the tubing that ties the two frames together, shop floor is level and smooth. Once I had the body centered, I could spin the body with one hand. The guy that painted my 65 liked it so much that he bought one for himself. I actually used it to install the engine and trans from underneath by raising and tilting the body. I thought it was money well spent, figured it would take a week or more to fabricate one even if I had plans. I’m pretty happy with it, plan on using it again with my 64.
