Chris,
I do not have a kit yet. I have been researching some different options and trying to piece parts together. I have been having a hard time finding disc brakes for a 3/4 ton. I am looking at using rotors from a 01-07 3500 Van and calipers from an 80's era K10 truck. As far as the caliper brackets, I was looking at making my own or buying some. Still not sure yet.
