UPDATE:
I cheaped out and bought the RockAuto master and slave, $102 shipped to my door and it got here in 2 days. Turns out its the exact same as the one that came out of my car, same brand name, MADE IN THE USA stamped on it in the same places, exact same part. Doesnt say DELCO on it anywhere and its missing one little white tag, but either way, Im happy.
OLD MASTER
NEW MASTER
Took 1 1/2 hours to fix a problem Ive dealt with for the past 3 years. I can hold the clutch in for 5 minutes and no pressure bleeds off. Hardest parts: Getting the steering shaft off and wiggling the master/slave combo around the headers, steering column, and brake booster. Still havnt gotten the GOD DAMN STEERING SHAFT BACK ON. Tomorrow.

Without the valvetrain done I think id be chasing your taillights, your auto will get me to the 60 and 330 especially since I've never seen a .400 pro tree before. I'm gonna need all the help I can get, but at least now I can sit at the line with the clutch in!

Just wanted to add a couple pointers for those who find this thread in a search looking for HOW TO's:
1. Tilt the steering column up
2. Remove the steering shaft by removing the 11mm bolt and ALOT of prying with a screwdriver and swing it out of the way towards the front of the car
3. unclip the master cylinder reservoir from the clip, swing it down towards the header
4. Take off the 2 13mm bolts holding the master to the firewall under the dash with a deep well and a few extensions
5. take off the clip holding the master plunger to the clutch petal
6. take off the 2 13mm bolts holding the slave on with a 13mm deep well, then slip out the slave from the trans
7. pull the master out from the firewall and let it dangle, the bolts that hold it in is actually a squared U bolt, remove that U bolt and set it aside
TRICKY PART:
8. Finagle the slave from under the car up OVER the #7 primary, that is the ONLY SPOT it is big enough to slip through with Pacesetter LTs. It SUCKS and takes a while but youll get it
9. Going back and forth from below the car to above, slowly work the slave up and out of the top of the engine bay
When putting the new assembly in, DO NOT CUT THE PLASTIC RETAINING CLIP ON THE SLAVE, EVER, it breaks when you first push the clutch petal.
Assembly is just the reverse of disassembly.
