Detroit locker posi unit??

I think that is what I have in my car now. It was bought thru Randys ring and pinion about 5 years ago. I will fish out my receipt to double check. Anyone have one of these to know if there is a little slop in them like the detroit lockers?

the true track is different then the detroit locker i though you were talking about.. the true track will be smooth.
