Mine had their sliders on it from the factory. You notch but I went with a OEM GYTR set. Those sliders I have are for sale.
I have also a set of their LED front signals. Again, top notch and very bright. Only the top cote anodization is coming off. Not sure since I'm not the original purchaser, if they would warranty them. But the previous owner lived near salt water which may been a factor. I like them slot too and will resurface them
