4 gear B6D
 

Looking for a 4 gear stand-up to fit to a B6.1D. This means I am looking for the B6D stock transmission plus the 4 gear conversion parts (idler gear and shaft, box, plate), as the conversion parts on their own aren't much use to me (as the B6.1D is a 3 gear layback and most parts can't be used in a 4 gear stand-up)
Message me if you have one lying around (used or new)
