1967-72 Chevy Truck Model I.D.
We hope the following information on Axle, Transmission and Model identification will help many of you with your questions. Accuracy was a concern as we compiled this information. Because GM made so many scheduled as well as unscheduled changes, there is much discussion about these changes.
