The Paddock is the only link you have so far? Let me get you some more.
Here's a list:
Year one of course :
www.yearone.com
R/t Specialties :
http://www.rtspecialties.net/.
Just Dashes : (Dash pads hard to find)
http://www.justdashes.com/Index.htm
Those are a few I use. E-bodies have the largest aftermarket of all the mopars so finding parts is really quite easy. You should pick up a copy of Mopar Collectors guide or Mopar Muscle Magazine to help you find parts suppliers.
