Headers for 74 Dart Swinger 318

I've got a set of Thorley's that are over chassis for sale. 1-5/8 primaries, but 2.5" collector. They fit, but were pretty tight around the power steering. I guess I should say almost fit as after I got them in there wasn't enough clearance for the starter with a 727. They were made for the 904. Not sure if the starter will fit the manual bell housing and these headers though. Shoot me private message if your interested.
