Gear box question

My gear box is on its way out and I was considering the durango swap. I currently run 33's and dont forsee ever going any larger than that. Will the cherokee box hold up OK with 33's? Im asking cuz there dont seem to be any 98-99 durangos readily available in the area. Or is there any other vehicle i might be able snag a gear box out of and get away with doing this swap?

mine has done fine. i would re-enforce the frame rail while in there
