I purchased a fastback, 6R09A10605_. This is a 4 Speed car. The date on the door tag is 10J. I have questions on casting numbers. For example is the intake supposed to be a C60E or a C5AE? And should the Autolite carb be C5ZF (5ZF) or C6ZF (6ZF) on the toe tag? Since the car was built in 1965 as a 1966 model, are all casting number supposed to be C6 or are some possibly C5?
Thank you all!
