Sorry should read 1991.I'm confused. You say that you want to run an M103 out of the car. You say that you are building the complete drivetrain of a 2001 300E into a streetrod.
But a 2001 300E is not a 124 chassis vehicle, the subject of this forum.
And a 2001 300E certainly does not have an M103.
The motor needs to run in another vehicle in other words...and I need to know what needs to be taken out of the 124 shell to do that, but the absolute minimum.
