Sorry, I thought you were saying that the original was at a 1.5 pitch, I didn't catch the AROUND part.I forgot how the pitch goes... if it went on half way the pitch is really close.. try 1.25 or 1.75.Hardware stores will take back nuts that you can't (didn't) use as long as you provide a recipt.Make sure that you clean the threads of the bolt off before putting your nuts on. I had a problem with that before.As for the crown nut, I think somebody was thinking of the crown nut for the Axle, and I wasn't paying attention to the original post.Hit me up if you need anything, you already have my AIM screenname.
