This takes a bit of effort and patience (to cut holes in your fenders), but I think its worth it. Not cheap either, but it is cheaper than the side-mirrors with the turn-signal repeaters! I wrote this up last year, but I couldn't find it on PriusChat. Therefore, I'm posting it again. http://www.box.net/shared/9dc62z6acc
Wish I found that before I had mine installed. It would have helped a lot. I actually made my own templates. If anyone is interested in mine you can find them here. Oh and good job on your guide. http://priuschat.com/index.php?showtopic=1...&hl=side+marker
