Amg conversions usually had 4 speeds.There was a 1975 4 speed available on craigslist recently in the San Francisco area.The hard part of doing the conversion is finding a euro donor car.You need the clutch pedals,bell housing,trans,and shifter.Sometimes the parts come up on ebay as well.The last one I saw was in a euro 116 350SE.A list member from the SF area went and grabbed it as he had a similar vehicle.
