I used the floor stock brake pedal assembly. I fabricated (4) 7'' long posts that bolted a after market dual master adapter bracket. I threaded the posts into the booster then bolted the assembly to truck A custom made push rod threaded to the booster push rod. the posts were to push out the booster to clear the transmission mounted brake assembly. The master bolted up and lines were installed to the corresponding axles. The master floor access hole is under the seat.
