Mike,
I have the 8.8 unit in mine with 31 spline axels and a built Eaton posi unit. It is great but will scoot the left rear tire on a very slow tight turn like in my driveway or at an intersection. But nothing like a solid locker. If you are going to drive it and not just race, stay away from the solid lockers. Pictures please as Tru asked. Close ups as we want to inspect your welds. Within 1" should do.
