+ R 70 Judge,
Yea, those would be nice to work with. The 1 3/4 could be "close enough!" If it is ID. Not sure if OD. Away from my workdesk notes showing 060 wall stuff and ID OD. May even be nice to borrow awhile as a guide model that doesn't get altered, while building ss 304 flanges, setting pipes "laying" on their side to create a proper angle ( to promote a cut once fitment).
Imagine the 6-8 path inboard, and the 2-4 path outboard.. DS would want the 3-7 inboard, 1-5 outboard. Otherwise reshaped Ys, and some trick on the Sec exit, and past the header.
