Well all I can really say is avoid the chain parts stores. I used one and had to pull the tranny a year later to do it again. Second slave came from BCB.

I can get sachs clutch slave & T/bearing set the clutch master that my supplier has is doorman not thrilled with doorman but at least that's the master not the slave. Thanks it felt like a never ending search to find. Let me know if I can help with parts.
Sounds like you're on the right track. I remember when my first slave let go. The night before a big run. Took the wind out of my sails for sure! It started to fail while I was waiting on my Atlas to show up, so I babied it along for a little while and replaced it with the BCB one when the Atlas went in.
