Actually that does not look like the pined version.  Never can be 100% sure from a picture but that looks like the version with a plasma cut holes in gear then rosette weld fills the holes.  You can send just the input shaft.  I'll give you some instructions on how to check for proper end play on it.  You may have to change the thickness or number of nylon snubber washers on nose of prop shaft.
