Anybody using scarebird disc conversion

Just wondering if anyone out there has used the scarebird disc brake conversion. I have a 70 dart with manual drums all around. I was wondering how hard the conversion is ie, master cylinder, proportioning valve ect. Another question I have is whether mopar steel wheels will clear the Chevy celebrity calipers that you use with the conversion. I want to stay small bolt patter as I have a number of 14 inch and 15 inch steelies that I could use. I really do not want to go with ralleye wheels. Any info would be helpful.
