Hy The 38 Special, the serial number, or as it's currently called the V.I.N. [vehicle identification number] is the number that is on the tag on the cowl, and sometimes stamped on the frame above the front axle. The engine serial number, the number stamped on the pad behind distributer on the old sixes, was used in some jurisdictions as the V.I.N., but when the parts books ask for a serial number or V.I.N. they want the number off of the cowl tag, hope that helps.
