I didn't say that. I said the factory Mercedes alternators used with serpentine belts can't use the older V-belt pulley. The shafts are different. The 143A is AL0162X, the 150A is AL0766X.

The AL129X is not a Mercedes alternator, that's from a Saab. It was never used on any Mercedes. And yes, it works fine on an OM617 or M117 engine with V-belts. more details on the AL129X swap (for OM61x/M117/etc) are in this thread.
