Having said that, you would also need some exhaust work if you were to change it over.

Mines a 3 spd also (back on the column again) and sometimes I think that's the best theft deterrent around. Nobody knows how to drive them anymore!

Yup every time I've taken it somewhere for service I've had to coach them on how to shift it!
