Door hinge questions??

Yes the detent wheels go on the bottom on the drivers side but the pin head is on the top, passenger side has the detent wheels on the top as well as the pin head. Top hinges are pinhead on top and the pin goes in from the opposite side per side. The markings mean nothing for direction.

Now why anyone would put used hinges on their car is beyond me, it's like fixing the problem with the same problem.....

And yes when I rebuild them I completely disassemble and fix everything including the detent and paint with epoxy so your door not only opens and closes properly but detents.....
