Yep, halfmile nailed it. That's why I didn't put any lengths with the angles. The hard part for me, and why it took 3 tries to get right, was the shallow bends. Getting the angle wasn't bad, but getting the offplane angle right at the same time was tricky. 3.5" CLR on the bending die is what matched the back of my seat. The brand seat I used is KE motorsports.
