i am running a detroit nospin, in my 88", but it has the stock rover diff in the rear, which has a different carrier than the salisbury. this locker is designed for the salisbury, essentially a dana60? which im not too familiar with. I bought my axles, and drive flanges from Great Basin Rovers, out of utah. They also carry this locker, as well as upgraded shafts etc.. but personally i dont have much experience with salisbury diffs. After i installed the locker, 24 spline conversion from gbr for the rover axle, i havent broken a shaft yet, or had any problems, and im running 34 tsl's.
