1969 Dodge Dart GTS w/383

Yes it should have headrests. I have checked out dozens of 69 Darts and they all had VIN numbers in the proper places, unless they had sheet metal replaced. My 69 GTS 383 4-speed car was wrecked by me in the front in 1979 and has all NOS sheetmetal for the core support, so no number there. I have seen a few with full original quarters replaced and the numbers were usually from the car the quarters came from. Most people did not take the time to transfer the numbers.
