Differences from 1967-1972

[semperfidoordie]

Hey everyone as most of you know I'm in the Marine Corps. I do intelligence which is basically briefing through powerpoint the officers as to what the bad guys are doing. I am teaching all my younger Marines how to become good briefers and one of the ways we do this is to make "fun" briefs they can give on whatever they want. I'm starting off, being the senior guy I figure it's my part to show them the way. I am going to give one on the 67-72 Chevy pickup haha a passion close to all of our hearts. I was wanting a rundown of the major differences from 1967-1972. For all the years in between; example major diffs between 67-68 68-69 and so on. If you guys could help it would be greatly appreciated plus I'm putting pics so if you wanna throw in truck pics for me that'd be appreciated thanks
