I have a few questions about the possibility of putting an M120 into a 380SL

1) Will a 380SL transmission phyisically bold to an M120 Engine.

2) If so are there any ways to strengthen the 380SL trans.

3) Is a 560SL trans built stronger than a 380SL trans.

4) Assuming I have to get a transmission out of a S or SL 600. Is it likely that this transmission 4 speed or 5 speed version, will bolt in place and mate up to my drive shaft.

5) For the electronic controls on the S or SL 600 transmission, are they a seperate wire harness and computer. Or are they integrated with the engine controls.

6) Does anyone know the rear end ratio of an SL600 or S600

7) Is there any easy way of matching the speedo gears for mismatched rearends.

8) Does anyone have any dimensions for an M120 Engine.

Thank You
John Roncallo
