will a KXF piston fit a kfx?

I get a good deal on Vertex pistons, but they only make them for the kxf and not the kfx. I know the heads are interchangable, are the pistons?

cross reference the stock piston part numbers or the cylinder part numbers

I think there is a 1 or 2mm difference in the size of diameter in the wrist pin
