Yeti, having holes in the pivot is a must to keep body where you want it, but you guy's need to think "outside the bug"
. It doesn't matter were you mount the body as long as the center of gravity is close to pivot point of rotisserie. I've drawn a "manual cad" version (don't have new auto cad '07 loaded at house yet). The dotted line is the pivot point. You just have to find the "sweet spot" to balance the body. The tubes that attach to the pivot have holes to help "find" the center point. Pictures are better than words IMO.
