I need retractable seatbelt mounting pics

Does anybody have pics of their retractable seatbelt mounts? Most of the old links are dead or the pics have been removed. I am specifically looking for where you mounted and how you mounted the retractable part. I can see just by the size of the retractable mechanism that it has to be moved back closer to the back seat just to make the backseat accessible. I am guessing most folks that did this put their anchor into floorboard and used a right angle bracket with the floorboard. That is about the only way I can see how you would keep the seatbelt from binding up. I want to get an idea of how much space it would take up. I am debating doing the Wesco retractable vs their non-retractable.
