67 Fastback

I have a 67 Barracuda fastback. It is a original 383 Formula S, It now has a built 440. Does anyone have a K frame from a 68 to 72 "A" body for sale? Also, Does anyone make direct fit front brake rotors with 4 1/2 inch bolt Pattern. All of the upgrades I see are for drum spindles mine has factory disc. This is the first "A" body that I have owned so I am not sure what parts will swap out.

I would talk to Moser eng. about the brakes. They may be able to redrill the rotor for the 4.5" patern
