I had that same question. Lincolnmania and Gadget advised me to look for a 83-91 8.8 rear end with the "K" code. It comes with 3.55's and limited slip. Dont quote me. Im just going from memory. There are human Encyclopedias lurching within the forum and will probably be responding shortly. You have come to the right place.Vehicle: 1965 Pontiac Catalina (fastback 2+2)
Chasis: 1982 Ford LTD Country Squire
Drivetrain: 302 V8 carb, AOD, 8.8 with 3.08 gears.
Big Brake swap and front suspension completed.

easiest to find is the K code rear out of a tow package car. If you're looking to change the gearing without swapping the whole rear assembly, you can put any set of gears in there you'd like. Traction lock units can be installed too.
A related question is what sort of driving do you do, and what are your goals for the car? Possibly the 3.55 isn't the best choice for you,86 Lincoln Town Car (Galactica).

Me thinks your application *might* be a little bit different than the rest of us. I personally like my 3.73 posi set up.Originally posted by mrltd View PostWhat happened here?Comment

3.55 and 3.73 are my favorites for a panther
