door hinge ?

Recommended Posts

I would like to know if the top and bottom door hinges are the same and therefore interchangeable?

I don't know what vehicle you have, but normally, the lower hinge is longer in order to align with the upper hinge when the door curves in at the bottom.

Folks above are correct:  The front doors on the truck cabs 'taper in' at the bottom, so the lower hinge is longer.  The parts book for the 34 truck, KC cab (which, as far as the doors are concerned, is the same as the 33 HC, which is NOT true of the passenger car doors between those two years), lists different numbers for the two hinges:  399073 for the upper hinge assembly (right side) and 399079 for the lower hinge assembly (right side).  Note that it also appears that there were some changes to the upper hinge assembly number, depending upon when the cab was made.  SMB

OK, thank you for all the replies, I will just have to figure out how to straighten out my hinges as they are obviously bent out of shape.

Are you sure they are bent?   Fitting the doors to the door opening with them will reveal if they are damaged or not. If need be they are easy to bend. 

Luck.    John
