tailgate upper hinges, differant lengths?

[CS1972]

The tailgate hinges on my truck are at the point where the arms connect are tired (extremely loose and catch on the tail light trim/metal), so I found and bought NOS OEM GM labeled 3924246 and 3924245 (old stickers intact). I painted them and went to install only to find the same problem as bautino95, both were exactly 1" different in length. When installed it looked like my tail gate had become a massive spoiler. Did I search and find the wrong part #'s or ???????

Pics are tail gate with old hinges laying flat, new hinges - spoiler effect and the last pic showing the difference in length.
