I just the other day saw something on ebay that caught my attention. It is a front brake conversion kit from 60 to 0 brakes. The item #220526691613 is a complete system including the knuckles for $385.00.
It looks like even if you are just replacing parts it might be the way to go. If anyone has any experience with this product or 60to0 brakes please reply. It looks to good to be true for the price.
