This information is gleaned from the five engines that I have here and the 1929-1957 Parts Book.
The comm., util (1st Ser) front outer mounting bolts from 1937 to 1955 were 3/8”-24 x 1 7/8" drilled
carriage head pn.3701135 used with a ‘slotted’ nut.
The inner front truck cushion mounting bolts as I mentioned were part of the front plate but were
7/16”-20 x 2” un-drilled and were the same from 1937 to at least 1953. I have nothing newer here to
compare the front plates to and the parts book gives no description of the attached hardware.
