On my 1988 b2200 2wd truck I was in the process of replacing my pitman arm. When I somehow screwed up the thread on the nut. the bolt seems fine but i can't find the details on the nut size to find a new nut to replace it. If anyone can tell me what the size and pitch of the nut is would be great.

 

Take the bolt into a parts store or engineering shop, they can measure or compare the bolt thread.
