Does GM Autotrac always come with automatic locking rear differential? How
do I know if I have a locking rear differential?

Didn't you post this question a couple of times the other day Tom - or was
it someone else? No matter - there were a couple of answers posted over the
past two days or so.

Jack up rear wheels(both). Put in neutral w/emer. brake off.
Have
someone hold one rear wheel still while you try to spin the opposite one.
If it spins ok, it's unlocked; if it is extremely difficult to turn, or will
not turn, it is locked.
