Reuse the A/C compressor -- If you have a working one by all means do not remove the compressor from the lines. instead unbolt the compressor from the engine and just move it out of the way with the lines still attached. This saves you from getting stuck with r134.

Also I used the alternator and bracket from the W126.


One more thing... use the air cleaner from the W126. The inlet on the W123 cleaner is too small in diameter for the fresh air pipe coming from the front of the car.


Take your time and replace the motor mounts (rubber parts) as well as the engine shocks and you will be fine.

Oh and by the way, Take off the black cap on the ALDA and crank it up (out) about 1/2 turn. The W123 engine is tuned WAY down and will not motivate a heavier W126 body.
