You would have to use a normal booster on a dual res. master, which I've done on my V-8 48. It's mounted under the floor in the stock location using the orignal clutch/brake pedals' bell crank. Now would be the time to do it on yours since the body is off. Let me know if you want to persue this further. I'll let you know what master I used and what you need to look for in a booster,
