OK, a list of 10 bolt parts I found.
There is a large seal that is completely rubber on the front axle that goes between the stub shaft and the spindle. It is Motor City (Advance Auto) part number S722109.

The seal that is on the back side of the front hubs that goes between it and the spindle is Motor City number S471271.

The inner axle seals for the front axle next to the carrier bearings is GM part number 6273977.



U-bolts for front axle:
The long one that goes around the case is a difficult one to find. MotorMite (the "HELP!" company) makes one that is 9.5" long and 3 3/16" in diameter. It is made out of 5/8" stock. The number is 35672 on the box but on the receipt it came up as 41140 which looks like a CarQuest number.
For the other three I used CarQuest part number 41132. It is 8 5/8" long and 3" in diameter. It is also made out of 5/8" stock.
