Yes, I know... those are v1 shafts you have listed, which would require the V1 pistons from VRP
I'm trying to show you that there are 2 different style shock shafts for the AE B5M. So it's easy to order the wrong pistons if your not aware.
I bought a used B5M and ordered some taper pistons, but before I placed my order I checked to see what shafts I had, and turned out the previous owner had put in the upgraded V2 shafts with the screw mount.
