is a 67 k10 worth any more than a later one

[bigrigpardo]

I am going to try and pickup two trucks this weekend one is a 72 c10 parts truck and the other is a running 1967 factory k10 long bed that the guy uses as a daily and a plow truck for his driveway during the winter. if it isn't rotted to death would being a 67 verses a more common 69-72 make it worth more and what do you think it may be worth. it has some usual rust but for nj standards its all fixable
