72 doors vs. 69

[rsavage]

I have a line on some new aftermarket Goodmark doors that are for 72 that I could pick up for my 69 Blazer fairly reasonably and save my body guy a good amount of time (obviously they would be cut for the Blazer. My question (beyond the hole below the vent) is what else is different? Are the inner doors punched out differently? Will all my 69 door regulators, handle hardware, and door panels bolt on to those shells? Nylon Inserts for the 69 armrests there or at least the square holes? I don't want to use 72 hardware and door panels. What can you tell me? Thanks.
