#370225 is the differential pinion gear (5.26). The differential side gears (5.28) which the axles slide through have 16 teeth on the outside and 17 splines inside corresponding to the 17 splines on the axle ends. I have a chance to buy a NOS RH axle, GM 3652342 but the description says 10 splines and the picture shows that as well so I dont know if what I pulled out of my '46 1/2 ton is original or the guy selling the part is wrong in his pn. To confuse things more, I have a lead on a NOS 3656862 which was the RH axle used in earlier years ('41) but didn't know if I should try it instead. It has 17 splines and appears to be the same length.Thanks.
