We have used the geo tracker booster with a GM vet master.This will work well with the brakes you have but will be spongy with larger callipers. You will have to widen the mount holed in the Master and cut a piece of tubing to fit the plunger in the master to the push rod in the booster. You will make a gasket to seal the back of the master. this will give you good peddle feel and just the right amount of boost. I have photos of a finished system if you wont them.
