My Dad has been in Mopar/Dodge parts since 1967. He has numerous items, some old, some new, that show Mopar and DC. Motor Parts goes way back as one poster has mentioned.
And yes, the youngsters have a harder time getting parts than the older hands. My Dad has sooo many connections from over the years, plus old reference books; he finds all kinds of odd ball stuff in warehouses and dusty old nooks and shelves.
