Getting a similar Shop Manual

We have a 67 barracuda as well, the 67 FSM covers SOME of what you will need. Because 67 was the 1st year for 2nd gen cudas, Ma Mopar dropped the ball and didnt put anything specific to the cudas in there. Shortly after the release they came out with a supplement that covers barracuda specific info. Shoot me your email and I can send you copies. But yes get 67 FSM for starters. More than just cosmetics changed from year to year with these gen of cudas.
Hello all again. Coming at you guys with another questionably dumb question.
So I have a 67 barracuda and I'm wanting the (you should definitely have this) shop manual for it. However, the 1967 shop manual lists several non-barracuda cars for 67, and a barracuda under the 1966 section (unsure why but I know a 66 barracuda is NOT what I want, different gen car). SO should I get the 67 manual and just know that all the cars are basically the same? OR should I get a 68 manual b/c the 68 barracuda will be 99% the same car minus some cosmetic details.
Wanting to use it for some questionably able DIY work (engine, rear end, brakes, normal servicing, etc.)
