Anyone have any info on this? Says it applies to IO-360 M1A’s but I don’t know if we have the SAP Crankshaft?

Thanks.

They typically make replacement parts, so it would probably only apply if you replaced your crankshaft with one of theirs.

SAP crankshaft is an aftermarket crank by Superior Air Parts. You likely have the OEM Lycoming crank unless you had a prop-strike and had to buy a non-OEM crank.
