1966-1967 Plymouth Service Manual

You might want to keep it. I have one as well, but had to pick up a Service Bulletin to get specific info on the Barracuda (#67-25-6). It mostly covers the sheet metal, interior parts, and mechanical items that are specific to the Barracuda only (not even 31 pages long). So if you need info on anything else, you would have to refer to the service manual to get it.
