You can start with Year One but they are mainly a middleman for other parts companies. Their customer service is top notch though. There is a master list of Mopar vendors out there but I cannot remember where to find that source. You may be able to do a quick search on the net for it unless someone in the group has it. You can also get the Paddock's catalog to start off with as well as Legendary's for interior parts. Some items are not being reproduced and of course, you will need to seek those out from private parties. Good luck.
