brillhill18 is referring to a 1954 Chevrolet truck. What are you all referring to?
Brian,
I have three 1954 Chevrolet trucks, on all but one the threads on the posts were badly mangled. I had some threads that were so mangled that I could not remove the nuts without either destroying the nut or destroying the post. The measure I gave above was for a good post with clean threads. I used a stainless steel nut as a test-fit (it fit tightly but it smoothly went up and down the entire length of the post). I then measured the diameter with a bolt gauge and the threads with a thread gauge.
