Hello all, just recently bought what I was told to be an eaton truetrac diff for my 7.5 10-bolt. I don't think it's what I got but I'm not 100% sure. I tried looking on eatons site but I can't find the particular part number anywhere. I have edb 39147 on one side and 31k3 on the other. See pics and someone please tell me what I have! Thanks!!

Those probably go for 350-400 new so id say you didnt do bad. It is likely a cone style clutch posi so you'll need the friction modifier in the oil.
