I was lucky to find a 86 E300 at my local pick a part I pull off every thing need it for the conversion and I said lucky because Mercedes only imported around 300 of this E300 in 1986. It can be done using parts from a 190E the only parts different in the 190 are the drive shaft and the transmission support and the flywheel has to be able to take a 9 inch clutch disc my is 9.5 no problems so far after almost two years
