The RAMMAN conversion

I'm thinking about calling the RAMMAN to convert my 74 Duster front drum brakes to disc and keep the small bolt pattern. No point in buying new wheels (current, 15" Cragar Mags with small bolt pattern) if I don't have to. I've read a few things on here where people may have had problems with The RAMMAN. Is there anybody out there that might have a success story to share with The RAMMAN or should I stand clear?
