It's the same one man. The Astro shaft always needs to be modified.
X3 - Its just not worth the hassle for $40 if one is a no hassle unit. The reason you dont want to have to modify the astro shaft is if you have to replace it -- if you do have to replace one-- having to go and modify one versus just putting ti in and bolting it up is well worth the extra $40
It comes with the clevis and pin. You just have to thread the rod and screw the end on.
