Try making a posi unit out of a single legger,..You'll have almost $900.00 in it by the time you purchase,
the posi unit, correct case installation kit, and labor at your favorite shop. Around here, its $450 for the clutch pack posi,(Jegs)
another $135 for the install kit (Jegs) and $250 labor at the Ring and Pinion Shop. Plus what you paid for the single legger unit.
New Hi quality units Ive seen,are like $1450.00 now.
