If you're referring to the crank seal on the oil pump housing/crankshaft pulley gear side of the engine, the part appears to be 91212-PR7-A01 (not AO1, number 0 not letter O). I don't think your part number exists at all.
If you want the crank seal at the transmission side ("rear main seal"), the part number is either 91214-PL2-003 or 91214-PL2-004. I think it depends on the manufacturer of the seal, not sure if it matters.
All parts are the same between A/T and M/T.
