A trip to a Pick-nPull type yard.. get ya a set of 3.73 or 3.42 gears out of a 1500 Chevy Suburban or Pick up (8.5) , a Posi unit out of 71-81 F body (28 spline 8.5) if on a budget.
With more budget a posi from a 90's Impala or Roadmaster (30 spline 8.5) and a new set of 30 spline axles

if budget allows more get all new stuff for a bunch more money
