Dual Master Cylinder with Brake Booster

Looking to replace original master cylinder, with a dual master cylinder and a brake booster. I heard that you can just go to a junk yard and find an old fox body mustang, or really most older fords, and just use that master cylinder and brake booster? I cant remeber the years that i was told you could use. But i was just wondering how easy the installion was, and how much modifications you have to do? Any info on the subject is greatly needed

Whoever told you that was lying through his teeth. The only boosters that will fit the 64-66 are the original OEM or the Master Power repro of it, and a few more modern types made specifically for this conversion. It is probably possible to modify and adapt several different boosters to work, but flipping burgers to earn the money for a good one would take a lot less time, and be a lot safer when you were done. BTW, the Master Power is the only one that works with stock clutch linkage. I also mounts a dual master cylinder, if you order it that way.
