Thanks OGB for the info. Since the truck came with a 9" rear it must be
the heavy duty model. It also has US NAVY printed on the doors and tailgate.
It doesn't have a dual master cylinder so I know it's not a 1967, but does your
info say what year the truck is? That's one of the things I was most interested in. It also has the hump in the back of the engine cover and back of the cab down near the floor. My cousin also has an eco pickup, but his does not have this hump.
Thanks for the reply......
