Hi Guys
Over the years I have found various parts for my Chevy CMPs (all those strange little Ford parts used on CMPs) on the MAC's Antique Auto Parts web site
http://macsautoparts.com/ . One of those web sites you want to book mark no matter if you are working on a Ford or Chevy CMP also believe that you will find common Ford Parts for the Carriers as well.
I've found them to be a good company to work with and their online catalog is pretty easy to use. Though I do wish they would add dimensions to some of their stuff would make it easier to confirm parts.
Cheers Phil
