Working on a 79 project that I acquired mid build. So, I have been learning as I go. The 5 lug 4 wheel disc is done. I have P valve gutted and plugged, front brake line kit and the LRS-2005A type booster. The booster application says it will work with all fox years 79-93. My question is the master cylinder? The 84-86 SVO master cylinder applications are only for 84, 5&6. The booster push rod is not adjustable. Will this master cylinder LRS-2140E work on my booster? Or will the OEM power brake master cylinder I have for the booster with the line adjuster be enough? I really don't want to buy another booster. (Already put on car so I can't return) I believe I need the line adapter for the passenger side also. Last question. Now because the P valve acts only as a distribution block, which port is best used for the rear brake supply? Rear port opposite the plug? Thank You!
