On paper, a seemingly easy solution is swapping a '69 CJ four-wheel-drum master cylinder for a '69 Camaro unit with four-wheel manual discs. The frame-mounting bolt patterns and port sides are the same, and the Camaro's bore is 1/8-inch larger for more fluid flow. However, notice the width difference-the Jeep frame would need to be modified to clear the Camaro MC's lid clip.
