Jeffko,
Don't know where your leak is from, but if you need a new master cylinder, Summit sells them, Wilwood part number 260-1304. It is an exact swap out, no problems. Ask your wife, kid, or neighbor to sit in your car and depress the clutch and keep holding it down. You should be able to observe the system and spot the leak. I never keep my clutch depressed at red lights, I always put it in neutral while I wait. I don't think the small master cylinders for four and six cylinder engines were designed to handle the back pressure of a large V-8 clutch, and that constant pressure may be a reason for the seals to fail. I had to replace my master cylinder after 1 year and 5000 miles due to leaky seals.
As for the slave, I had the same bleeding issue. Do not go to Ford or Mazda for that part. Go to NAPA or Auto Zone or the likes and ask for a 1988 Mazda B2500 pick-up truck. Then ask if they have the mirror image of that one. I don't have the part number for the original slave, but the part number for the better slave is S1031 (the original Backdraft supplied one is only one number different, either S1030 or S1032). Anyway, my replacement is an aftermarket OEM spec slave from New Generation Clutch Systems. The bleed valve is at the top and it solves your bleeding problem. Good Luck.
