These were popular pickups. My Pop had 3 that I know of and maybe more back in the day. Someone likely has an axle that is looking for a home. The 3.73:1 was the common axle for the Dana 41/F1 combination. If a 4-speed was installed, they usually used the lower gears. The Dana 41 gears and axles from a Mercury in the 1949 to early 1950 time frame had 3.91:1 gears and are interchangeable with the exception of the spring pads. A person could just use the guts from one if they didn't want to swap pads out. Dana 44 axles from late 50 thru 52 are a bolt in if you don't mind 3.92:1 gears.

New gears and carriers are available for the Dana 44 but I don't think they will fit in the Dana 41. This would be expensive though since a person has to change carriers for the taller gear sets and that adds up to big bucks just for the new parts required alone.
