so my 87's rear stock D44 is non posi and no locker either. :bawl:i want a Detraoit Tru Trac locker, but this thing is 99% street driven. it only sees offroad in Hunting season. is it true that a Tru Trac is a posi unit for the most part and not a locker? I dont really want a full locker, I would like a posi. And you cant beat Detroit. if i get it, will my tires chirp on tight turns in parking lots, etc. like a regualr locker or...... ive messeged some members on here about their Tru Tracs and im still a little uinclear. if i went offraod more, I would buy a full case Detroit or a lock right. Thanks,
