Help needed to identify these headers

Looking closely at the pictures provided in the listing by the seller, I could be persuaded the pri tubes are 2" based on the mic of the OD. However, the tape measure across the collector is well short of 3" - nothing close to the 4" of your prior set. I did find an old Hooker catalog from 1977 on eBay but I'm not $125 curious. I've got a set of the big tube, 4" collectors for a B/E body car but I'm building a clone of a SS Hemi Dart. I briefly considered cutting & modifying the B/E headers (like a good hotrodder!) to get what I need but figure it's easier to get some TTIs and move on to the next part of the build. Thanks for your knowledge!
