Seems like there are some of the Mopar resto vendors that sell pins/bushings now. Much of what you might find in the HELP! rack are for GM applications, as we sold the heck out of GM pickup truck door hinge pin/bushings. They usually had one long pin and the bushings. The pin diameter was somewhat common, but the bushings could be different. IF the OD of the bushings is larger than where they go in your Chrysler hinges, a little drill bit action can fix that.
Later models use two shorter pins with the same bushings, I believe. Take measurements of what you have (pin diameter and OD of the existing bushings) and see if you can match them up. ALSO, you might look in the Dorman Parts website, under your particular application.
