My california special scripts needed replacing. The old ones are being held on by #4 flat speed nuts on both CS's. I hate flat speed nuts. Is this the correct attachment method? I am thinking of taking a 4-40 die and threading the posts, then using a #4 nut, flatwasher, and split washer. The scripts go on and off in a flash (i tested this out on one of the old scripts which is pretty much junk; this is good for waxing as the detailing on and around the scripts is painful) u can replace these with the flat speed washers for shows. the threaded posts on the scripts make it easy to switch.
