Dearborn Lift-E 6 ft disc

Like many people, I'm sure, I am looking for good salvage parts for my E series tandem disc harrow:

I need a spool - part # 111777
a ribbed spool - 111778
four 16" smooth discs - 111781
and an upper and lower bearing cap - 111779 & 111780

Plus a couple of nuts to go on the 1" round axles.Does anyone know what size nut I need to buy for the axles? Two of the old square nuts cracked and they seem to have a fine thread - when I look for 1" nuts in the hardware stores and farm supply stores, they all seem to have a course thread.

Appreciate any guidance anyone can offer. Thanks!
