Brake Swap Master Cylinder

easy swap,
get some '73+ spindles or FMJ and some '76+ A, FMJ calipers, then a '73-'74 A body master with power brakes and then you will have large boar calipers with small boar master. The result is a nice firm pedal that stops the car very nicely. Make sure to use the proper prop valve as well, either the FMJ one or '73+ A body disk brake one. I also recommend an adjustable valve for the rear so you can get them to lock when you want.
