^ sliders look OEM which is what you want. The CS frame vs BMWP seat frame are very similar. The rails seem different that what I have seen. I do have a spare frame and rails from the Recaro built BMWP seat that I've tried to get replicated. It's just to intricate for any fab shops in my area. One benefit of the BMWP frame and rails is how low it sits. Pics coming
