67-72 parts interchangeable?

[AJLChase]

Was wondering, I may be picking up a rust free cab that's had all the of the internal sheet metal done. It's a 67 cab with Bezel which looks to have the choke and it also has the small rear window. The rest of the truck will be a 69. One main reason I'm getting the cab is because it is done inside and has a title which my 69 doesn't. So, I was wondering if (most) body parts are interchangeable between the years? I like the 69 front clip and bumper, but I like the 67 fenders w/o the side markers. Would that work? Bolt on? Or modification? The bezel I would like to use the 69 being that it has the extra gauges, but can I just yank out the choke assembly and be done with it? One more thing, 67 cab with VIN and 69 Body....so what does it make it? Identity crisis? haha
