Getting a similar Shop Manual

Well, let's split hairs then Al, rolling out a brand new platform of car without a service manual isnt dropping the ball?
Hmmm they only did 1 run of FSM manuals? No 67 manuals got printed in 68 or 9?
Since it was my response you are questioning, IMO they dropped the ball. Ever see ANY 67 manuals with bulletin, supplement, whatever u want to call it?
Not even in a 67 manual printed in 69.
Were talking the difference in thickness of blond vs brunette pu$$y hairs here.
Theres enough stuff in the supplement that warrants the OP having it INCLUDING elec schematics lol, ask me how I know.
OP BEWARE, not everything at Mymopar.com is factory including the schematics. Pain in the ***!
I wouldn't exactly say Mopar dropped the ball, The Barracuda was a late entry car for 67, production started October 31, 1966. So it is hard to say if the literature was even ready for the press when the manual went to press.

The Supplement was issued as a Service Bulletin, it includes everything unique to the Barracuda, otherwise use the Valiant in the regular Manual
