Correct me if I'm wrong, but during the VIN derivative stamping process, the engine and trans were stamped at the same time using the same stamp. Is this right?No, not always.
Would two separate gang dies be used, at times? For instance, someone at the front of the engine to stamp the block, and someone at the back to stamp the trans.? If so, did they have a separate source of individual dies for changing the VIN numbers?
The reason I ask is that I'm seeing a discrepancy between one of the digits - block to trans.
