1965 Ford F600 help
 

Hi all, I have an actual heavy duty truck, seen here: https://imgur.com/a/lOHmE
I'm looking for parts for this thing but none of the popular online stores or box stores locally have the truck in their system, nor do they have the engine size, as this isnt the FE engine, but the HD engine instead and only offered in F500+ vehicles. Does anyone have a source for parts on this old steel monster?
