I have one for $250 (firm). It's a 3.08 posi out of a 71. Complete rear. Brian

Thanks for the reply.

Is it a five lug avle unit?

Coil or leaf spring unit?

Do you know the condition or type of posi unit?

How can you determine if it is a Dana 60?

The rear I have is a 71 5 lug rear. Dana 60 is a 3/4 ton rear. Posi appears to be in decent shape. Truck had 80k miles on it. I didn't apply a torque set-up to see what the slippage was on the posi unit.

Thanks for the reply.

I asked several people what a Dana 60 was. They did not know.

What is the actual terminology to describe the rear in these trucks? Are they referred to a Chevy 12 bolt?

I am agonizing over replacing only the diff unit or the complete housing.

I think that the breakaway torque on a chevy posi is 75 ft/lb.

Thanks again,

Frank
