72/68 door question

[70CHEVYBB]

i just bought a 72 c10 and want to put a 68 front clip on it. my doors are in ok shape but i might just buy new doors. Should i put 68 doors on or do I have to stay with 72 doors? I know there is some differences and something about a extra screw on the inside but i could use some input on what to do?

Thanks, Wes

2 main differences is that the 1972 doors have a screw to hold the door top together below the wing window. Also the window regulators and door handle mechanisms have longer posts on them to accommodate the molded plastic door panels.
