Don't think yours was the same one....yours was a 906 port for an RB with STAGE VI which (if you think about it) will only work on that combo.
I sold it to a guy in Canada who is looking for exactly that....remember any othe RB/Stage VI manifold would need spacers to makethe manifold fit.....what i think is that the 337 will bolt on a non raised port MW without spacers and should therefore (trying to confirm it will) fit on a B with Stage VI's.
