I have an '07. I am thinking about getting an undertail and also swingarm extensions for a winter project. What undertail keeps the stock tail light? I don't want to spend a ton of cash. I already have the Clear Alternatives integrated LED kit on my bike and want it kept that way. I am also thinking about swingarm extensions, maybe a 4"-6" stretch. I want to make sure that whatever I get is compatible with each other. Any opinion would be appreciated.
