I got lucky my truck had a G80 in it with that gear ratio so the swap was straight forward. I gave the old axle away as trying to sell an axle with 270k on it would be a hard sell.

My bet is you have 3.73 and g80 , 2nd would be 3.42 open
And what's you reason for wanting to add a posi ? If it were me I would consider a lunch box locker if you are open rear , but Iam a off road guy , have yet to have any negative experience with a locker in the rear my self on the street
