explorer 8.8 in an a-body: experience needed

the exploder diff is pretty strong , mine went 450,000 km and was still going stong when i sold the 1998 exploder . Posi in it never gave me trouble and I really abused that truck , now the trans and transfer case was replaced 3 times , that diff was STRONG . Just blew my 8 3/4 , so not impressed with it .
