Rear Differential Help with Specs Please

Hi Guys and Gals, I tried to search but cant find exactly what I need. Need to know the type of differntial for rear how many courts, and if I need to buy the Gasket, only Ford or Napa has it, I have a non limited slip 2002 6.8l 3.73 gears, thanks in advance!!

Ps Ford Quoted me 80-90 for the job, is that good, He said that is for the non limited slip.

JWISE, you do not need a gasket. You need a glue like material that you put on the edges of your pumpkin and it will dry. I changed the fluid in my rear end like 2 or 3 months ago and bought RP 75w140 for the rear. I bout 3 quarts (the pumpkin takes 3.5 so buy 4 quarts). I paid 17.00 per a quart (i got ripped off) but they have it on the internet for 12.00 a quart. The Royal Purple gear oil already has the friction modifier in it. So for limited slip or Non limited slip, youll be fine if you decede to use this oil. But i would recommend it because i had a hummin noise in my rear end and when i changed it out with the RP, it went away. If you need any help just ask or PM me!

Ok, let us kno how it goes. RP is VERY hard to find around town. But, the only place that sells it it ia advanced auto parts, but they may have to order it. They had to order mine and it only took a day. But its alot more expensive at AA and ull save if u order it on the internet. I didnt order it on the internet because i wanted it right away as my rear end was leakin oil.
