erics said:I'm just putting a 12/79 tub (1980 model year) on a 2/79 truck (1979 model year) and the 1979 model year fuel door opens to the rear of the truck (lock front/hinge rear) while the 1980 model year is opposite (lock rear/hinge front).
Don't know if model years 81-83 changed fuel door configuration again, but I'd guess not. So the combination of the square bezel and the fuel door leads me to say it's a 1979 model year.
any detail junkies out there have addition/correction on this? Pimp?
