George,
No, the 1968 isn't too different. There was a change in the body design at the front and back of the cars in 1970, but most of the major mechanical components remained the same from 1967 - 1976. Obviously if you're looking for something specific to your 68 like, say, taillight part numbers, then you're out of luck. These 1970 - 1972 manuals will definitely serve you well. I'll figure out a way to get these manuals to you, one way or another. Sit tight.
