Q&A: What is the year, make, and model of the muscle car John Milner drives in the movie, “American Graffiti?”

Question by Da Austrian Oak: What is the year, make, and model of the muscle car John Milner drives in the movie, “American Graffiti?”
It’s the movie George Lucas wrote and directed that I believe came out in 1970 about young adults in the early 60’s. John Milner is the character’s name that owns the car. Harrison Ford, the actor, is in the movie and in one scene calls the car “piss yellow,” when he’s trying to get Milner to race. I’m pretty sure the car is customized, but that car rules. If only I knew the year, make, and model. If I could have any two cars in the world, you might call me crazy, but it would be a brand new one of those and a brand new 1987 Buick Grand National, no mileage, which of course is impossible. Big differences in muscle cars, yeah, I know. If you know at least the make and or model (there’s no way you’re gonna know the year if you don’t even know the make or model), tell me that. If you don’t know any of these, tell me what you thought about the movie. If you haven’t seen the movie and you like movies/cars about/from the late 50’s/early 60’s, then rent it dammit. Wolfman Jack in in it!
