I have owned my 66 Chevy C 10 Fleetside longbed for over 20 years. Restored it in 1993 and it needs it again. I have a pair of good bed sides but I don't want to mess with the old bed components such as the all the steel below the wood bed. Are new pieces available now? Quality and fitment? I would like to just lower a completely rebuilt bed onto the frame of the truck. My old bed is completely shot, I have welded so many patch panels onto it that it looks like a puzzle underneath and behind the bed sides.
