sorry I don't know this. I lost the nut that holds the steering wheel to the column. My guess is it's 5/8 course standard right thread. Looking to install my tuff wheel and adaptor and I discovered I lost the nut sometime over the past six years, lol
Going to see if I can find one in the specialty bins at Lowes or Home Depot. Thought the may be one inthe adaptor kit but no such luck
