Engine Replacement Or Fix Piston Ring

[1KWIKSIX]

Looking for a good replacement metric oil pump housing, does Melling make one?
Would prefer something made in the Good Ole USA if possible.
Trying to stay away from the off shore made stuff (Silver Seal)
Would anyone have a part number and source availavble

Thanks
Dave
