The Stovebolt Site Forums The Parking Lot Big Bolts Vin & Parts Plate Decode '66 GMC 4000 (I Think..)

Engoi,

The 6066 GMC Guy decoding worked for my GMC 5500 truck except for the part about the wheelbase. Your pictures looks like my 64 GMC 1500 pickup rather than my 66 GMC 5500 truck, but this could be a difference between models that year. I hope Bill can be of more help.
