Right on guys. I'll try to find some time to play around with the pedal and linkage this week just to make sure it's all lined up like it's supposed to. I doubt very much I played with the master, but there's no harm in pulling it out just to see. I replaced the slave cylinder back in 2010/2011 -- and back then (unbeknownst to me at the time) the clutch was so worn out that the rod-length on the new slave was keeping that fork from retreating all the way... so in my mind at the time I needed to modify the new slave cylinder to make it work correctly... I ended up drilling that dish the rod sits in just enough so that the slave could sit flush with the fork lever.
Since I'm a little older and (arguably) wiser now, I knew that with a new clutch/pressure-disc going in, the hackneyed slave cylinder had to go, which is why I put in a new one at the same time I did this job. They're cheap enough, and there's an Autozone hub 45 minutes from my house that has pretty much anything I'd ever need for this car in stock, so it was an easy decision.
The clutch master was replaced at a later date... sometime between then and now... which is why I don't remember fiddling with it.
@EuroDat Yeah dude, it feels pretty good that I was able to take apart a transmission, replace the broken bits, throw it all back together, and have it work. It really puts that $700-900 rebuild quote into perspective! I think I got out of this whole thing for somewhere in the neighborhood of $120 if you include specialty tools and replacement parts (along with new gear oil) and don't count the clutch/pressure-plate.
@Zed Head The clutch and pressure-plate came as a kit -- the clutch brand is Parault I believe, and the pressure plate is from Exedy. The new throw-out bearing was OEM (Koyo? Does that sound right? I chucked most of the boxes after I was done with everything -- the replacement parts have all been sitting on a shelf for a few years, so no chance of warranty-claims on any of it should it all go suddenly awry...)
Now I just need to go and knock on some wood or something... I'm superstitious and I sure I hope I haven't jinxed the whole car by singing my own praises!
Thanks again for all of the help and insights, team.
Oh, and @Dave WM I look forward to hearing how you progress on your end too! I've been so wrapped up in my own project I haven't seen how yours is coming.
