Both pivot 180 degrees vertically at the end, and can be firmly locked in to any position. Both have three slots to increase clamping positioning, may also be clamped down with c-clamps. This is the bar you'll need for the wings. Your surfaces not parallel, no problem.

That is if you have our drill bar.
