72' doors

[67chevytodd]

I found a 72' short wheel base step side that has been rolled. The truck has low miles and I would like to rebuild it. I think I can just weld a different top on the cab, but my problem is with the doors. What is the difference between the 1972 doors vs. 67-71 doors? I have 2 sets of the 67-71 doors, what would have to be done to them to use them on the 72' cab? -- Or whould I be better off finding 72' doors? Thanks for the help, Todd
