Thanks Bill,
Yes, I have a couple of pictures that I took last night, but after reading more today, I need to take another picture of the right side of the front pinion housing (dropout?) I will post all the pictures tonight when I get home.
I neglected to mention that the rear cover has 10 bolts and the front cover also has 10 bolts. It looks as though I can take out the front pinion support(?)
I should also count the bolts on the ring gear I guess. This information might make it easier to identify. I was looking for markings/ numbers on the left side, but I believe I might find what I'm looking for on the right side.
Right now I'm in search of the axle seals, and as always- my first trip to the local autoparts store ended with me ordering seals that don't fit. Fortunately, we pulled the old seal out of the right side and 'National 5801' was stamped on the old seal face. I am trying to cross-reference this old part now.
More later- I'll post some pictures.

Chris
