Dart on a rotisserie

Theoretically, I could still jack it up another couple of inches to get the full clearance, but it wouldn't be a secure position (i.e. with the bolts through the vertical pedestal to lock it in). I'd be operating on the jacks; something I'm not comfortable doing. If you look at the photos, there are 3 positions in the pedestal to bolt it through. Yes, I am in the highest bolted position. That really hasn't been a problem for me because I seldom have a need to put the car in a full upside/down position. It is no problem rotating from one "stop" to the other that give me probably 340 degrees of actual rotation access. If I absolutely need to go the full 360, I just have to clear those set screws in the connecting member.
