1967 Mustang Brake & Fuel Line Fastener Kit | Hardtop, 6-Cyl, 1-Piece Brake Line

This 1967 Mustang brake and fuel line fastener kit is engineered specifically for 6-cylinder hardtop models equipped with a 1-piece brake line layout. Each fastener in this kit is an OEM-style reproduction matched to the correct Ford engineering number, finish, and fit — ensuring authentic restoration and clean, accurate line routing.
Using factory-correct coatings including phosphate & oil, .0002 zinc & wax, black dipspin, and olive drab dipspin, this kit restores the underbody and frame-line retainers exactly the way Ford assembled them in 1967.
Ideal for concours restorations, high-quality driver builds, and OEM-correct repairs.
