Removable luggage rack and pockets

Hello! I bought a removable luggage carrier for softails up to year 99. How can I mount it? The safety lock sits on the turn signal and the thread is too short to leave the recording in between. I would also like to have the saddle bags mounted, whose holder is also worn out at the other end. Certainly there is a solution here, but I have no experience with the parts, but need the pleasure for a tour. Thanks, Thomas
