These are Harley. Think they are FLH lowers. Can be found on bBay used or new. Several aftermarket folks make them. The HD chrome has held up to abuse and neglect. Eventually I set them with just one bolt securing the wing on the high end of the forktube. The tab for the upper fix point can be just left there or cut off. The lower tip just clears the blinker. I reset the blinker out with one bolt to hold it in place. They helped me a lot. Quiet the ride, no wobbling. It don't look the best but they work.
