66 Fury III power booster
 

I'm having trouble finding a power booster for my 66 Fury III. I have the old style master cylinder that has a single line out to the block where it separates into 3 lines, there are 4 bolts that attach the master cylinder rather than the 2 for the newer styles. Can I use a newer style power booster with the newer style master cylinder with 2 lines out? It wouldn't be hard to reroute the lines. Has anyone done this? Is there a source for power boosters for these? I have tried all the auto parts stores, Speedway, Summit, and all of the online guys. Is there a rebuild kit still available for these?
