Have you ever rode or drove a car with a Detroit locker? If not you should before deciding
I got one ride in a 1965 Mustang Shelby GT350 with a Detroit locker in it, the owner got on it a little making a left turn and I thought he broke the rear end and he laughed saying that cracking, jerking and popping was normal for that type rear end
A good type clutch type posi is always my choice over a Detroit locker posi unit every time
I put a 35 spline spool and axles in my old 8 3/4 for street use until I bent the housing bad enough to break the welds off of the ladder bars mounts welded onto the rear end axle tubes
That would probably not happen with a clutch type posi
