Sure Grip Cone Type Spider Gears.

Auburn bought the Borg-Warner design, with their only major change being a 1-piece case. The Auburn pin can definitely be used, but I'm not 100% sure about the gears themselves. The Auburn kit for a new pin and spiders is their number 541012, but it's apparently not available at the moment. It may be discontinued. It's in the catalog .pdf but doesn't seem to work on their site.
