I have a brand new 6 speed (S6S 420G) correct for 840 and 540 (E34) sitting with a friend in Germany.
I was going to do a conversion from auto to manual but have cash flow issues and need to seel
This could be handy for someone with a worn out box or for a manual conversion.
A rebuilt change over sells for $4700 in Germany so check around and make me a sensible offer. I can have it shipped worldwide
