Anyone here have any experience with a hydroboost system refitted to a classic GM A body. I've seen some positive results posted on an Olds site. I have a hydroboost on a 1 ton GM van and it has a great rock hard pedal, and right now brakes. I have clearance problems with a standard PD booster and thought I'd try hydroboost. I did notice that new Mustangs use hydroboost and it works well. Thanks Jarhead
