Ted, I think he's referring to the VIN numbers that are stamped in a couple of places on the car. Normally there's one on the upper left rad support, and one on the trunk lip, underneath the trunk lid seal on the left side about 1/2 way between the rear curve of the trunk and the front of the lid. Sometimes the locations vary depending on the mfg. year and body style of the car.
Is that the info you were looking for?
