Sure fire way number 2: Even though it is a Plymouth Barracuda Operator's Manual, there is an order form in the back to get your $6 (including postage and handling) factory service manual for Dodge.

Or maybe I'm wrong and the NOS or originals actually did offer Dodge, not Plymouth, service manuals?

But probably not, because I must have ordered my $6 Plymouth service manual by tearing out the perforated order form in the back of my original 1969 Plymouth Barracuda Operator's Manual. I'll dig it out in a day or so and post photos.

Stippled and perforated are not synonymous.
