Good news, Mike.

Here's a tip I learned the hard way: The 'snout' of the pumpkin, where 
the rear driveshaft yolk slides onto the pinion shaft splines, is 
beveled on the inside.  The big seal that seals the pinion shaft should 
be installed with its edge even with the INSIDE edge of the bevel (about 
a eighth of an inch in).  I installed one with the seal even with the 
end of the snout, and it leaked like crazy because the seal wasn't 
riding on the proper part of the yolk.
