Need help to ID my axle and the gearing, now that I have the diff open. I could not find any numbers on the axle. I am sure the numbers are there, but they allude me so far. NAPA has seals for HO33 / HO35 and spicer/dana (40 if I recall). I presume I have the HO33/35. I dont know the differences to ID? Also interested in the ratio in case I need parts or new axle. Attached is the picture. Markings on the ring gear: GM 3763466, 13, 44 followed by what I think is a date code. My book tells me there was a 3.90 or an optional 3.38 gearing.
Interested in learning more for a my notebook so I can buy replacement parts when needed. HB
