Center of balance on a Rotisserie

I put the center of the pivot even with the center of the firewall and tail panel as a starting point. Then I fine tune it until I can basically spin it with one hand and there are no points where it want to roll over on its own. Take your time now and it will make your restoration so much more enjoyable rather than fighting an out of balance rotisserie. Expect to spend about 2 hours getting it dialed in perfectly. Well worth it in the end.
