Looking at a 1976 2002 that has the "Certification Label" on the driver's door edge that shows the VIN. The label that is affixed to the upper steering column shows a number that doesn't match the VIN on the door edge. I'm assuming that these two numbers are supposed to match. All the labels under the hood are either gone or have been painted over. Car runs well and is clean. Current owner and previous owner can't shed any light on this. Advice please.
