I have a 3.55 cone style sure grip for sale. I switched to a 3.23. The 3.55 was making a slight humming on acceleration so I put in new carrier bearings after I pulled it. It also has a 1350 pinion yoke and a new pinion seal. I am asking $400.00. It is located in Johnstown, PA. I could bring it to Carlisle Chrysler Nats.
