I have added the following AMC manuals to the website that are available to download for free. These are the Service Specifications Handbooks. They are pocket size booklets that contain tune-up, service specifications and other technical data to include (from the 1970 TOC):
Model and Body Styles
Tread Width and Wheelbase
Emission Control Systems
Transmissions; manual, Shift Command
Steering - Front Suspension
1968 AMC Service Specifications Handbook - Javelin, Rebel, Ambassador, Rambler American. Note: As a result of being introduced in Feb. of 1968 the AMX and 390 are not covered in the 1968 booklet - use the 1969 booklet for that information.
1969 AMC Service Specifications Handbook - Includes Rambler, Rebel, AMX, Javelin, Ambassador.
1970 AMC Service Specifications Handbook - Covers the Hornet, Rebel, AMX, Javelin, Ambassador.
