Right on the mark tclederman! That's what I was talking about in my post about the rarity of the '54-'55 'burb or panel sending unit/pick up tube assembly. And speaking of gas tanks - the '47-'53 1/2 ton 'burb or panel are the same as the '47-'48 1/2 ton pick up. The 1 ton gas tank from the panel or pick up '47-'53 has different dimensions because the 1 ton frame is narrower. The 1/2 ton tank will not fit the 1 ton.
