Rusty,
There are three long and three shorter screws. (Three go through the bung and tap into the tank.) I believe the sizes are M5X12 and M5X30, .80 pitch on all. That is from memory so I would suggest pull one of each and take them down and have them matched. I used black metric allen heads like the stainless steel ones I removed. I just hazed the tops with satin black paint let them dry, and topped with just a little clear lacquer. I installed with a metric allen socket and they held up fine. I also used a little blue thread locker on them to be sure. You can always touch up with a small aritst paint brush if necessary. Good luck, one of the best $4.00 mods I have done. By the way I checked those Kuryakyn mirrors out in the J&P catalog, kind of leaning that way.
