what type of thread on 231 studs.
 

I've lost my t-case nuts somehow during removal/install of my aw4 ,And was wondering what thread the 9/16th nuts need to be ,so maybe I might find them at the hardware store and get the beast rolling.

answering my own question...3/8 24 fine thread on nut end...and 3/8 16 course thread at transfer case end of stud .
