I have a '50 F-1 with a Dana 41 rear end. The tag on the differential reads "W 51 / 13" which calculates to be 3.92. The shop manual says a 3.92 would be 47 / 12. Do you think the gears have been replaced or is this just a setup that wasn't listed in the manual?

These F-1 trucks only had the 3.92 or the 4.10 ratios.

Could be a set out of a Dana 44. Still works out to be a 3.92
