60-66 shortbed frame question?

[travz500]

I was told today that the 67-72 frame was the same as the 60-66 is this true?? I am having trouble finding a 4x4 shortbed frame 60-66 have found one and set up a time twice and he never answers phone when it comes time to meet up and its 2 hours away so i am not just going to drive and hope he is around but I have found a few 67-72 shortbed 4x4 frames here lately and if they are the same i will get one hope someone has dealt with this before
