Early AMC Cranks
Not all AMC crank flange bores are the same. Early motors 1971 and previous - as well as those with automatic transmissions around this era - featured a ~1.8" step (image, right) or a shallow recess instead of a ~1.8" centering bore as found on later AMC V8 engines. This distinction is important to make if adapting to Ford style transmissions. All early and late cranks (in our documentation) feature a pilot bushing bore that is just over 1" in diameter whether they have the above step-bore, or not.
