Crankshaft Seal Part Number O-320 D1A

Could someone confirm this is the Lycoming part number I need for a Lycoming O-320 D1A 160hp = LW-13792. Seems to many options, over size, under size, split, no split....I am a bit confused and plan to drive to AS and pickup needed part and Dow adhesive tomorrow. Thanks

That is the correct part number. There is also an oversized version of this seal. It is part number LW-13792-P50. The oversized seal would only be used in the event that the crankcase has had to be machined 50 thousands of an inch larger in the seal bore, of the crankcases.
