DISC BRAKE SET UP, SBP FOR 69 BARRACUDA

Looking for a complete small bolt pattern disc brake set up (Kelsey Hayes?) for my 69 Barracuda. I already know everyone wants the 4.5" pattern and 15" wheels but my wheels and tires are brand new so I would like to keep them and spare the extra expense of replacing them. I don't race the car its just a cruiser, let me know what you have..........thanks
