    I would like to upgrade my brake master cylinder.
    I have a 1995 Tahoe LS, 350, 4wd (automatic) with a Kelsey Hayes ABS module (completely stock) and I would like to do the NBS to OBS upgrade. One video I watched mentioned HydroBoost. What is HydroBoost and how can I determine if I have it? I plan on going with the AC Delco master cylinder. I live on an island in Southeast Alaska and our only parts dealer is NAPA and will most likely have to order one since they probably won't have one in stock. Can anyone give me a NAPA part number for one with HydroBoost and one without?
    Thank you very much.
