Anyone know of a source for the plastic sheath that covers the seat belt as it passes through the rear seat cushions of a foxbody? Perhaps another ford vehicle of the same era that used the same part? Latemodel only carries the fronts and I cannot find them anywhere else online. Part is stamped with 359104A regency-2. This is a link that shows it. https://www.hood.de/img1/xxl/4583/45838235.jpg
