Door hinges

[twin 72's]

Will the upper and lower door hinges off of a 74 work on a 72

Yes . You can even use the 75 - up B Bodies .

Thanks wasn't sure they looked similar but have different part number stampings

[hemihead]

The change in part numbers i believe came because of the change in body styles or a slight modification of some kind . The 71 - 73 used a Coil spring in the lower hinge and I think starting in 74 they went to a S - type spring .
