So Ive done a manual conversion in my old 300D and that didnt seem to bad. However that car Had manual gearbox that was actually made for the car. Now I would like to convert my 350 to a manual. I really dont like having such high revs on the highway with only the 4spd automatic and I quite prefer a manual gearbox to an auto any day. Anyone know what transmission I could use? I found a 190D with a manual gearbox (dunno if its a 4 or 5spd) and was probably going to use that since its Benz and everything should fit right in. Ideas anyone??
