1955-1st series?
If yes, it is like the 1954.

Yes, the 1-ton radiator was either 0.5" thicker/deeper than a 1/2 or 3/4 ton (2.5" vs 2.0"); and, the optional 1-ton radiator was 3.0" thick/deep.

The 1-ton radiator had a different mounting frame.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
