funny...mine came today as well (not to mention it was $30 cheaper than originally since they can ship via UPS now!)...I was just geting on here to find the posts I read a while back about installation tips...
so, I'm guessing I'll need a 1/2" bi-metal hole saw, some washers to fill the gaps...correct?
also, I know this was talked about before, but why I couldn't use a 1/2" clevis pin and a hitchpin clip instead of the bolt/nut/washer? I know it only takes a few minutes to get the bar off, but I use my slip on forks alot, and it would nice to remove the bar quickly.
