Default Looking to change my differential

I have a Ford 9" 31 spline detroit locker in my turbo'd 67 firebird. The locker is obviously not very street friendly. I was considering some type of limited slip and ran across the speedmaster torque worm. Tried adding a link but was not successful. Looking for some advice before I pull the trigger. Thanks in advance

I run the SOFT LOCKER 9" center section and no issues.
We ran the old locker in our boosted mustang for one week and then removed it.

I would probably have less of an issue if it didn't unlock at all similar to a spool. It's pretty harsh, bucks the car and makes you think something has broke. It's probably compounded for me by the fact that it's a stick car.
