door pins and door seal differences between 72 and 74

According to everything I have seen, 67 thru 74 uses the same door hinges.

The pin kits are a bit universal and you have to drill out the existing hinges to install bushings where there were none from the factory on one of the hinges.

I can not find info about 75 and 76 hinges so I suspect they were different some how.

Iirc @MoparLeo is the hinge rebuilder here on FABO and he might be able to shed some light for you.
