i used my b13 ones on my b13 when i did the swap.
just have to grind down the bar on one side or your shifter will look like its pushed over getting into first/2nd.
i may be wrong but im pretty sure you have to grind down a side of it to keep it right. or that is what i did.
the nx with p11 is grinded down and i didnt do this swap.
i did a b15 into my b13 vvl-t i use to have.
