I have an extra set of the Booth bolts for the front wheels if you are interested, great looking bolts. I just got the front wheels, because those are the ones that are easiest to see.
I got them, then almost immediately put spacers on the wheels and needed longer bolts. For what its worth, I have painted my stock bolts that I currently use with spacers. For me, paint does not last very long, especially if you are swapping rims very much like I do,
