Cab Differences 67-72?

[RaTTrap 68]

Hi

I was wondering what differences there were between the 67 thru 72 cabs.I know there is that "vent" at the door jamb on the later models,but was wondering if there were any more differences or anything stopping me from using my 67/68 front sheetmetal and doors on a later cab?

I will eventually need to find a "decent" cab to rebuild as the one on my 68 is well beyond repair,and would rather not use the one off my 67 while iam using it for daily trransportation.


Thanks
