bucket set sliders - bearing cage or cradle

My junior and I just took apart 3 seat tracks. One from each pair. The latest models have white nylon cages (that was 75 bench seat track). Short of doing a lot of measuring, those appear to fit the same steel rail form. They dont have the 1 extended limb either. Just larger overall. So... If you dont find exactly what you have, I probably have something that will get you beyond this and on to the next challenge. Hang in there, message me when you have to. Good luck
