Re: what year??

These trucks never had a round "door" for gas. They had a cap sticking out of the side of the bed until 1981 when they changed to the new style front end. That's when they added a door to hide the gas cap..

Ken, not true. Gas doors came out in 1978.

Re: what year??

The 78 in my avatar had a round hole and gas cap and it was definitely original .The truck was purchased May 23 ,1978 so it was at least a mid production year built truck . All of the 79's I have seen had the square lid . I think it started in 79 but it may have been a late 78 option . Frank

Yes, some 78's had the exposed cap, but some also had the square door (I owned one). Sometime during the year they switched.

Re: what year??

Yeah, I know I should know. For some reason when he talked about "round" doors it just didn't sound right. Must be my sometymers kicking in...
