1310, 29 spline, U-bolt yoke.  This is similar to the stock yoke on most Dana 60s.  Our design raises the u-joint from the mounting surface by 1/4" compared to an OE yoke; this allows for increased drive line angle before binding.  It uses U-bolts to fasten the u-joints instead of straps. 

We also take the extra step when you buy the kit.  If you don't know already, you'll find out that the OE pinion nut for the Dana 60 uses a 1-5/16" socket.  What most people don't know is that there's a jump in the wall thickness of a socket when you go from 1-1/4" to 1-5/16.  The result of this increased wall thickness is a socket that's too fat to fit inside of the yoke.  Most people grind down the socket to fit, or buy a Snap On one, but we came up with a better solution.  The nut that comes with our kit threads right onto the pinion, but uses a 1-1/4" socket!  No expensive tools, no fabrication, it just works.  Please keep in mind that until you get our nut on there (i.e. to get your nut off) you will need to do something special.
