I figured I would post this for future reference since there is some doubt on this seal. If you ever have the rear output seal (rear driveshaft) go bad, the skf23000 works perfect. Napa is suppose to be able to have it but my local napa was worthless. I ended up buying one off amazon with overnight shipping for $20. Compared to the 50-60 mopar seal. You will need a 3-1/2" or 4" piece of pipe to install it. But it goes right in.
