Jack the rear up, both wheels off of the ground, floor, or what-have-you.
Put the trans in neutral, and then spin by hand one of the wheels...if the opposite-side wheel/tire spins the SAME way, you have the trac-lok, if it spins the opposite way, you have an open diff.

Of course, if you do happen to have the locker, and it's worn the hell out, it may spin like an open diff.

BTW, does your car have quad shocks, and/or the rear swaybar?
Usually, the trac-loc cars have those, but not always.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

All of the 87 3.8L cars got an open rear 3.27.
It's Gumby's fault.

I thought a locking differential was optional if you had the heavy duty/towing package?
