You might want tro consider the Jim's mustang conversion kit. I have it on the front of my 65' FB and it works well. It is a Granda swap kit with spindles that are modified to accept the stock Mustang tie rods. The whole kit was like 500 bucks and it comes with rebuilt calipers, fresh rotors, lines, etc. In the long run you will save yourself a lot of time and money starting with nice fresh stuff instead of taking junk parts and rebuilding them etc. I kow the cost might be more then the cost of the used parts, but when you add the new lines, pads, turning the rotors, etc..you come out ahead with fresh goodies. Just my opinion...but a good way to get the single piston front conversion I think. I've done it and it works.
