Anyone who wants to update it is welcome to it. This list took several years to compile when I was in the parts business and I published it here several years after that. Since I'm not in that business anymore, I don't maintain the list's accuracy any longer. As I see it, you would need to check each part number against the dealer database to verify its current availability, unless someone has a more wiz-bang, less labor intensive method of verification.
Maybe Dave at Roseville Moparts could provide a more updated list since they are a Chrysler dealer, they do stock a very large catalog of restoration parts, and they offer a parts locator service.
