Little rear end help please (Dana 60)

[Scottcoda]

I am just about finished with my winter projects and cannot wait to get her on the road for the first time since all my major changes! One of the major changes was putting taller gears in my non-posi Dana 60, The truck originally had 4.56 and I went to a 3.54, I replaced the yolk, carrier, ring and pinion.. She is ready to roll!!! But what happens?? Something awesome!!! A person I have just met says they have a posi-rear 8 lug Dana 4.10 from a 68 3/4 ton truck sitting behind his shed!!! The way this person has been is just fantastic, He loves these trucks and loves to see good things happen with them so I think he might let it go for a song.. My question is will the new parts from my non-posi Dana 60 fit into his posi Dana 60?? I would love to have a posi in my truck!!! Wish I met this guy before I completed the work on my Dana!! Any insight would be awesome!!!
