If it's a standard "base" Fleetwood, it has an open 2:56. Option code GM8.

If it's a Brougham package Fleetwood, it has an open 3:08. Option code GU4.

If it (rare) is tow package equipped, it has an open 3:73. Option code GT4.

Those were the 3 ratios and their option code (on the trunklid sticker) for the '93 model year, all of which are "open" diffs, as a locker/posi was never available on the Fleetwood. It's pretty easy to tell just from the model of the car, but also just look at your SPID label on the trunklid underneath.

Yup, factory towing package is identified by "V4P" on the SPID in the trunk. Yes, very rare. On the internet looking for people I have found 4 total including mine. And so far, no 1993's.

I don't know if you could get posi in 1993, but look for G80.
