Threads are good, the bolt is at a machine shop which they tried to retap the nut but ended up breaking it in half, believe they said the thread was 8-36? Might order the tap from Brownels and try the spare nut I have. Thought I read somewhere they used a variety of different threads in different years. The bolt looks original and stays in place fine without the nut but thought I would like it to look original. Thanks for the suggestions.
