sorry TrevorC, i only found that your bearings for 1953-57 1Ton front are more difficult to source than the 1950-52 1Ton fronts.
INNER bearings OEM was a New Departure 909046, it is listed as 38 x 80 x 22 mm , ID/OD/Width, however many places like rounding the numbers, so if you are off by 0.1 mm on a replacement you won't be able to pound it in

SKF / Timken B46 replace DELCO, AC 909046
@ rockauto - SKF / Timken is interchanged with National B46 $74
OUTER bearing OEM was a New Departures 909045, size ID 23.03 mm,0.9065 in. OD 57.16 mm,2.2503 in. Wd 20.32 mm, 0.800 in. also called a ID 23 mm / OD 57mm / Wd 18mm
again, being off by a tiny amount going by listed rounded dimensions could be an issue if you don't have a perfect fit.

yup it's gonna cost a lot to replace all 4 bearings,
like i said before, do you need new bearings? that's a lot of beer money, i have many of these trucks and they all have good front bearings still and i do not anticipate needing to replace any soon.
these are all ball bearings like original
i was only able to find a roller drop in replacement for the OUTER front on the 1950-52 1Ton, National A37 is a roller replacement for a ND 909525, this roller bearing shouldn't fit the 53 and newer tho as the pasts lists do not show compatibility
