I'd like suggestions on particular Dura-Ace or equivalent Campy models I might use. I know Campy changed the configuration of their BB ends a t some point so the "newer" versions won't seat on my square taper Phil BB. Any suggestions will be appreciated.

I sez: When I worked for Bud's Bike Shop in the mid 70's, we did a number of conversions of Dura-Ace cranks to a 74mm bolt circle. My first Santana (serial #2) had a tandem version of this set up and it worked wonderfully. It utilized a double threaded post that was bolted with an allen head through the arm and a regular cheinring bolt to atttach the ring. It looked rather "frankenbike" but gave me a 28t small ring. I'll have to dig up some old photographs to scan someday...
