I have a question for those people running the Uglytruckling disk brake conversion. Can anyone answer this question or get me a picture of their hub? I am wondering what part of the stock hub they modify and how they attach the plate that the rotor attaches to. It appears that there is machined area, but also what looks like a ring welded to the hub? Anyways, here is a picture off their site with arrows pointing to the area I'd like a better detail of. Thanks.
