Hi again Don- I know a little about Rolls Royce-[did a 37 Limo] Masters of overengineering with less than average results!.....I hope you can find a booster that fits the bill-I just thought it was a mess of plumbing and wondered if it wouldn't be more future problems instead of an improvement.what does this rig weigh in at?if 3500 or so I wouldn;t be afraid to run a large bore Dual master cyl like a 1 ton suburban etc with no booster.GOOD LUCK-Kenny
