I just finished installing my rebuilt speedometer. I used knurled nuts and they are definitely the way to go. I had it zipped up in less than 10 minutes.

Thankfully somebody mentioned knurled nuts over wing nuts. The good thing about knurled nuts is they have a large conical opening that guides the threads onto the stud. Very easy.
