I have a silver and black Kartboy knob. But I want one of these. http://www2.kartboy.com/x4/product.php?productid=16200&cat=254&page=2
Oh, and I might be able to help you out. I have the stock knob from my old 02 yet. I might part with it. I only kept it for winter. But if I get the delrin knob from Kartboy, I won't need it anymore.
Looks just like the one in my LGT. I ordered a new knob that should be here Wednesday. If I like it, I'll sell you the pictured knob. Mines in great shape. PM me with an offer
