I just welded a 6" flex section in where the dp straightens before the flange and used the original flage, once you have a flex section in the dp the flange fits/works perfect.

Just pick a straight section big enough for the flex with enough clearance around it and reuse your flange. Make sure you keep the flange angle the same when you weld in the flex.
