Thanks Enda, was hoping you'd chip in.
Rubbish. I was under the impression this would be a straight forward fit!
Not sure I really want to change the gearbox. So would a prop shaft guy be able to chop and fabricate my 325 prop or do I need to get a 3.0 prop as well to cut and shut :(?
If it comes to it, are a 328 and M3 3.0 gearbox the same?
