There is a lot of labor involved in doing what you wish, if you have to pay someone to do it for you, $ could get out of control.

Look for brake parts places like NAPA, look for oldest gentleman there, search in old paper catalogues. Dual master will be on your own. Keep looking on here, someone will have done what you are doing.
