Without any disassembly, might an inexpensive digital caliper from Harbor Freight be a decent way to measure the ID and OD of the bushings, the OD of the pins, and the length of the pins?
In the realm of GM/Chevy parts, we dealt with hinge pins and bushings on pickup trucks ALL of the time. I never did measure them, but the OD of the pins all looked to be pretty much the same. It would not surprise me if the Mopar items might even be the same OD, with similar bushings.
ONE thing I did figure out, though, is that most people, when they open a door from the inside, FIRST push down on the armrest with their elbow! Kind of a reflex action as we want to push the door open. Which wears the hinges out in the process, sooner than later. It takes a bit of behavior modification, but if you just push out laterally with your elbow, rather than "putting your weight behind pushing down and then out", even the GM items do NOT wear nearly as quickly.
SAME thing when one approaches a hinged building door with a crossbar on it. As we walk up to a door that we suspect might be harder to open, we tend to hunker down, push down on that crossbar and then push the door open as we walk through the portal. With the lower crossbar location (not being in the vertical middle of the door), it tends to happen that way, moreso. Rather, just walk up to the door and push it horizontally with NO "pushing down" action. Works just as well!
KEY thing is to only use HORIZONTAL force to open door with.
Just some thoughts and experiences,
