No fenders. The flatbed actually sits on a 4x4" that is the length of the frame and is notched to fit the frame tight, and go over the hump over the axle. It then has L-shaped brackets attaching the bed to the wood frame.
I was talking with my dad and he said it was a pretty common thing to see wood framing over the steel truck frame to support the flatbeds in some of the older trucks. But that just could have been coincidence.
I cant say if it was something that actually came from the factory like that or if that was just something people did to adapt them to the trucks.
I was looking at another post at the bottom of this forum; Topic: 3/4-ton 3600 Factory Stakebed
and the first post has some pics on a flatbed that looks nearly the same as mine but there are differences.
Then again, a flatbed doesnt exactly have eye grabbing special effects! But I still love the way mine looks!
Thanks
