This (currently disconnected) 2-speed rear end belongs to my wife's 1941 GMC 2.5 ton (CC403). Originally a fire truck, the Department disconnected it, leaving it in low range, since they had no one left who could operate it (1990's - kids today lol!). Seem like high range would be handier if I had to pick just one, for road speed (45 mph). Anyone know what it is?
