Russntustin,
What size '52 pick-up are you working with? Size might matter when talking about the frame braces for fuel tanks.
As OleBlue said, '47.5-'48 pick-ups and all 47.5-55.5 1/2 ton suburbans and panel trucks had fuel tanks between the frame (passenger side, forward of the rear axle). The suburban/panel trucks have two frame braces that go over the tank (maybe someone else knows if the 47.5-48 pickup had the same braces).
