Brake kit advice - 1968 mustang

[68fstbk]

I am wondering if anybody has any advice on setting up a 68 mustang for auto cross / mild track use. My current disc brake set up is sort of a hodge podge from the original owner of the car and I want to start fresh. I am looking for people's opinions or feedback on what kits they have had the best results from. I am far from having a huge budget, but i would like some confidence inspiring brakes. Looking to replace everything from the master cylinder down, still on stock 68 disc spindles with a 9" in the rear.

thanks!
