According to a friend who is Parts & Service Director for a Jeep dealership, the Mopar BBK kits have been discontinued. He says you can get the individual components but the pricing is crazy. Jacks my jaws as I have the Master/Booster kit installed and would like to be able to get a master if needed. FWIW, I searched Rock Auto some months ago and they did show the ability to get the master cylinder per the part number shown in the Mopar BBK parts list.
