Those SSBC 4 piston brake calipers are really nothing more than 66-67 Mustang Kelsey Hayes calipers with that hose mounting design, and location. The Mustangs used either 3/8 or 7/16 diameter threaded hoses into the caliper.
Find out what size your SSBC calipers are and look into hoses for a Mustang. I have a new 3/8 hose here, that measures 16 1/2 inch, if that helps you out any for your car. Jim V.
