I am offering a Lycoming O320 Oil Pump Housing.  The interior wall is scored, needing some clean up and polish.  There is one aluminum gear frozen (I didn't attempt to force movement).  As with everything I offer, this may be returned for a full refund, for any reason.  US Priority Mail for $8.80.

Certification status, production status and maintenance status on this part is unknown.  Buyer takes responsibility for determining suitability and legality of part installation.
