Yes, that is more or less the truth of the Deluxe above hard bags. No bolt-on clean is available, and thus the majority of people simply modify a set of guards to fit a different Softail or get one customised by a local fabrication shop. It’s not ideal, but it works.
I have been most successful in following up on classifieds, swap meets, and rider forums, those weird parts do appear more frequently than you might guess. When you wait around, there is something that will come in handy.
