Fuel Tank shapes - B Series

[LH Thread]

I'm working on a B-3-B that has a rectangular shaped tank and I came across another tank that is trapezoid shaped.  The trapezoid one came to me in a frame with misc parts on it so I'm not sure what model or year it is.  Can anyone identify the trapezoid one?  I'm considering using it if things will bolt up without too much trouble.

Should only be the one shape for the trucks under 1.5 ton.   While a different tank may bolt up, the filler neck and sending unit location appear to be different and may cause you issues.

Thanks for the link!  It sounds like I am looking at a 52 and a 53.  The mention of the different shaped frame crossmember checks out with the parts that I have.
