Check out www.hogrida.com if you like the the nearly bolted to the fender look. Great deal and product at $25.
I got this one for my Lo. You have to flatten it out a tiny bit to perfectly match the curve of the lo's fender, but it's very clean. I don't have my plate yet, still runnin' with the temp tag, so don't have a good pic to share.
Drag Specialties makes one very similar to the Harley Lay back license mount, but it comes with an extra wedge shaped rubber piece that gives you an option of less angle. I actually liked it that way, just a bit more upright. Looked better under the rack I thought.
just take the upright bracket off the factory one and bend it down and then bend the inspection sticker part down. you might have to change the bolts that hold the license plate to the mount out if you have the ones with the red reflectors and wing nuts. looks even better if you paint the whole thing black
+1 on the hogrida as well, had one on my Dyna, and picked one up for my Fatboy. I had to buy one 'cause the damn dealer that I traded my Dyna to wouldn't give it back (lol). Must have dug hogrida's product (lol again..)
