Yep, that sure looks like an original - the first pic below is what I "thought" would have been an original cover - I wonder if there's any difference... Doubt it, and your contents page matches the title of the book below. Interesting that it covers light and medium duty - but that is how they did the service manual in 69. Not so in 71-72. The second one below is a good companion to your chassis service manual - covers some more detailed overhaul procedures for a subset of things. But the one you have is the main one.
