NOS GMC Oil Filter Housing ID Help??

[GMCNUT]

I friend I buy NOS stuff from has sent me pictures of a NOS oil filter housing he found in a closed dealership and says someone years back wrote "GMC" on the box - I don't think I have a book that can tell me if this set of part numbers off the box would happen to be for a 60-66 V6 maybe? Does anyone have the ability to decode these part numbers for us?

Part Numbers are 5574670, 5574351 and 5575091

Found two of those in this album:

Tough to read, and the bottom of page will give the reference book. I put lines next to the numbers. Page does not list 5574670
