Is a '69 AMX considered a mopar A-body?

This is going to be foreign to me. A bigger learning curve that I should consider.

AMC used some of all of the "big three's stuff" in their cars. Starters from Ford, distributors from the Delco division of General Motors, Torqueflite transmissions from Chrysler and Turbo Hydramatics from General Motors. They also used Borg Warner manual transmissions, AMC corporate and Dana rear ends. Yes, you have a learning curve, but buy a factory service manual and that will make it "less curvy".
