10+ uses a different seat (MK-20/25), and the piston has a "tib" (thermal insulation bonnet) snapped on it (as you can see, those e-xxy pistons are different). The different seat needs a different seat carrier, the 10 seat will not work with the 10+ piston. There is also a spring alignment bushing that sits in the body for the 10+. IIRC, one of the o-rings at the seat is also not used.
The 10+ is not a sharp edged piston, the 10 is.....
I just learned a whole bunch of this while working on a 10+ that was sold as a 10 to me, and was also a complete wreck. Hence my inquiry of the spring should you abandon your quest....
