Hoping I can get some help with this. I dropped my top cap the other day and did not think much of it at the time because usually use a hybrid disk. When I went to screw in the top cap it would thread all the way down. Looks like I dinged the threading on the bottom of the top cap. Does anyone know where I can find a really good quality replacement, or someone who can rethread it? The only caps I've been able to find is a brass one, and really crappy looking ones on fasttech.
