The Fender tag decoder is back up
test-page – DodgeCharger.org
It was down for a while, but is now up on a test page. As discussed elsewhere, it may not be 100% accurate, but it's the best one I've found. Codes can be cross-referenced with list on other sites. As of this posting, mymopar.com has the page for codes for 62-68 down, they are changing some things there too. Seems to be some upgrading of software going on all...
