440 Duster with 2" TTI and Borgenson, does it fit?

TTI 1-7/8 is a B/E body header isn't it?

I would like to know more on this too... I do recall in the CPPA days they offered a 1 7/8 A body header. I had like one of the first sets of their 2" primary headers, man that brings back frustrating memories lol....
