I got an Acerbis supermoto fender. I wasn't sure how to handle the guide for the speedo cable (there is none on the Acerbis of course). I think I could have let it hang, but I didn't want to. I contemplated moving the old guide to the new fender, but I didn't want to risk screwing up two fenders and I wanted to keep the stock one useable (anyone want to buy a stock 08 fender?). Also, the guide is big and it would have been hard, maybe impossible to get it to fit. Then inspiration struck.
I will show you what I did, and there is a brief review of the new fender at the end.
The idea I had was that I could buy a cabinet handle and use it as the guide. Not on the same level as discovering a flaw in the string theory, but not a bad idea. Got one at ACE for about 2.50. So, I put a piece of paper over the old fender holes and rubbed them so they would mark the paper and made myself a guide. Then I drew the holes onto the sticker grid which came from Acerbis. Drilled and attached the "guide". Pictures:
Here are the fenders side by side:

Then I mounted the fender...had to drill one hole out a little bigger. No prob. Mounted up fine and got the speedo cable re-attached. Pictures of the mounted guide and the bike (I think the new fender looks nice):
It was raining/hailing so I only took a short ride (wanted to make sure the speedo was working), but I couldn't resist seeing how the new fender worked. Did a quick blast on the freeway. The difference is amazing. I wish I had done this a long time ago.
Cost of Mod:
$25 give or take from Amazon (free shipping)
$3 for the cabinet handle
Having ridden the bike the way it is now, I don't see how you could spend a better $28. Probably not a great fender for the mud, but if you use your bike like I do (on the road...unless the sandy/pebbly shoulders of HWY 1 count as off road...), then by all means, consider this a huge endorsement. Felt WAY more stable at speed.
