I will be needing 2 of the same joints. My 400 yoke uses the stock size joint,as well as the stock rear end, THe aluminum shaft uses larger
The ones that attach to the shaft are outer rings,THey measure1.185 in diamter and seems to be 3.61 or so across including the caps.
SO stock size on 1 side with outer (cap mounted rings)
and 1.185 X 3.61 with internal rings on shaft side
Thanks Again
