I have got a question for you folks in the form. To start off with, I have a 50 GMC truck and I have been working on. It is a bit of a homemade tow truck. But the reason I am here is that it was a 14bolt full float dually rear end. I am on the look for an anchor plate or saddle (herd it called both) that goes below the axle tube, I am also on the look for the top spacer that the square u-bolts sit on, on top of the leaf springs. The anchor plate I have is a cast metal with what look like 3681703 in it. I have searched that number but come up empty. Do you all have any idea where to look for a similar part that would work?
My '81 parts truck has the setup you are describing (14 bolt FF). The bottom casting is most likely a forged piece and also holds the rear sway bar. The "U" bolts are round on the sides but are formed square where they go over the top plate. The top plate also looks to be forged. These should be fairly easy to find at the local wrecking yards.
