Not sure what model of the Cessna 150 you have, you don't say. For all 150's up to and including the 150K (but not the A150K) the 1A100/MCM and the 1A101/DCM are both approved for the aircraft. If you have an Aerobat 150K, then the ONLY prop approved for it is the 1A101/DCM
Props with other letter combinations after the model number are designed to be used with a spacer for L and M models, and should be avoided as they cannot be used to replaced earlier "spacerless" models.
