So, I got my fender tip in the mail today and thought I would follow up in this thread with some photos of it.
First I will say that it is very well made. I made a crack about how much it costs.......well that's mostly because I'm pretty cheap. This is a nice heavy piece of cast metal. Chrome finish on it is real nice as well.
It came shipped on a piece of cardboard, vacuumed sealed. On the back side of the packaging is a paper template to lay on the fender to lay out the holes to drill into the fender in order to mount it. NO screws will show when this is mounted. The screws are welded (or cast) into the back side of the piece and will go through the holes you drill into your fender. There is a small plastic package that contains a couple of small washers and nuts to attach to the screws from the under side of the fender.
So....it looks like the best way to mount this is to drill the recommended holes and mount it as they have intended. I hate the idea of drilling into my bikes fender too but I think it is going to look real nice once mounted.
I hope these photos help show it well.
