Does anyone know if the door hinges for a 68 are different from a 69-79? I ordered a set of hinges from Classic Industries and they say they are the same for 62-79. I tried putting them on they seem to bind and they were different from the ones I took off. I just went onto Goodmark's site and they show a separate set of hinges for a 68 and they look more like the ones I took off. Any info would be great. Thanks in advance.
