Hey Jason, look at these old instructions. It says NOT to fit disc springs. How shabby! Do you use the disc springs from the original (procat) kit or the larger ones from the U857 diff screw kit? These seem stronger - they have the same external diameter as the thrust bearing. If you use these you can't fit the plastic shield over so I see why you use the foam thingy. Did you make it?
This is from the procat manual. Schumacher told me this is correct i.e. (( but I'm inclined to go with seeing as you're the king of vintage runners!
