1966 Barracuda disc brake swap

Krazykuda the 69 dart setup I have located includes R&L uca’s lca’s spindles rotors strut rods Kelsey Hays calipers tie rods center-link idler arm pitman arm dual m/c and proportioning valve. What would be a fair purchase price?
The steering linkage and strut rods won't work with your '66, but, everything else will. Control arms will just be spares. You don't need to change them. You mainly need everything from the spindles out and the hydraulics.
