This sytem is based on a 1957 F600. It likely fits other years of medium duty Fords, but I do not have that information. This system is meant for these mounting specs: 3.5" horizontal and 2.375" vertical.

This is a complete bolt in kit designed to work on 1950s Ford medium duty F600- and similar trucks that gives you a firewall mounted Super Duty hydroboost brake booster and master cylinder. It comes with mounting brackets, booster, master cylinder, steering plumbing, and brake line adapters for 7/16 tube nut which are commonly on 1/4" lines. 
 
Master Cylinder
This comes with a1.5" bore Super Duty master cylinder with driver side ports. This is a fairly large bore size and this gives a firm pedal feel. It works well with original drum brakes.

Booster
A 1999-2004 style Super Duty hydroboost booster is included. This is a powerful and reliable booster. It plumbs into a power steering pump with included 6AN hoses and fittings.

This setup puts out about 2000 psi as well as a large amount of fluid and should be a good match for medium duty drum brakes or moden disc brake conversions. It is significantly more powerful than an original system.
