Rear end diff rebuild price?

He said id need to swap the axels. How hard is that? I'm starting to think the posi isn't a must and I should stay with the peg leg. Has anyone had a problem getting there boat up the ramp and out of the water with peg leg on these trucks? Mines a lwb if it makes a diff...

Usually $250 to $350 for gear installs if Done in the vehicle (local 4 Wheel Parts).  Small shops in smaller markets may charge much more though.  I think "Drivetrain" shops consider themselves specialty and, as a result, charge a premium.  Larger markets, like Denver, have competition.

Sorry for bumping this, but how can you easily detect a posi unit diff from the junkyard? I'm also a one-wheeled peeler (G80) and would love the posi. There are a couple trucks at the junk, is the only way to pry open the diff cover? And if so, what am I looking for?
