You want a perfect springer front end for your dyna visit Jerri's springers here is the link he has a streetbob on there. Send him your bike info in a email and he will custom build you a front end read to go with a new rotor, brakes, and the whole shabang. Prices vary but a basic set up will run around 3K. This to me is an incredible low price. But it does leave you having to do all the work putting on the front end your self. He will even add tabs to the forks to prevent overturning and denting you gas tank. All you will have to do is add a new bearing cup assemble the brakes, and etc. If you havent taken and front end off I would suggest going to a reputable mechanic and let them do it. Make sure they are insured and dont trust your baby to just anyone. Thats why I started doing all my motor work 20 years ago. Heres the link http://www.jeris-springer.com/chrome_inverted.html
