The shock shafts, bottom and top shock caps, I don't remember if the spacers that go by or between the o-rings are the same or if they are different, shock collars, and o-ring for the top shock cap. So basically what you can use/share from the standard shocks are the springs, plastic shock bottom & the metal ball that goes into the shock bottom, o-rings, possibly the spacers between the o-rings, and shock oil if you really wanted to.
