Got to looking for some spiked tag bolts for my wife's 600 Kat and nopne of the local parts stores had them. Then I looked online and found them for about $10 pluss shipping for just 2 ! So I said the heck with it and made some myself. after a couple of design changes this is what I wound up with. Its the one holding the tag & bracket on, not the ones around the bracket. Sorry for the crappy cell phone pics but I was at work.
