Thanks Rollo. There is a guy in the forum who heat-bent the Corso pipe using an internal spring as a template to hold the concentricity while bending. Great technique. From what he states, and it came out very well. I'll copy his technique if I can't find an accurate aftermarket piece. Another method is to place a vertical slice from the bottom of the pipe up past the pipe's centerline, tweak-in the correct bend and weld it up. But I like the first (non-destructuve) method better.
