Now I have a issue with the clutch install
I installed a new clutch in my 1977 REPU and have run into some issues. I installed the new clutch assembly, put eveything back together to discover that the throw out bearing is not making contact with the "fingers" of the clutch housing/pressue plate. I pulled everything apart re-aligned the clutch and realized that when I tighten the housing down that its pulling the "fingers" on the housing in. Now when I bought the clutch I matched everything up with the old one and eveything was the same ,dimensionally and visually they were identical, the only thing I couldn't check was the clutch plate thickness since the old one was so worn down. I bought the clutch kit from a local O'Reilly's auto parts and am now wondering if there is a problem with thickness of the clutch plate but I am no expert on the Rotary's so thats why I am here. I didn't do anything to the flywheel other than measure the depth across it to make sure it wasn't warped, all the measurements were consistant all around the flywheel so I just scuffed it up with some emory cloth. I have pulled the transmission twice now and don't want to have to do it again, so if anybody has some ideas on what my problem is and could offer some kind of solution I would greatly appreciate it.

The fingers on the clutch pressure plate are suppose to go down when you tighten the bolts. The arm that moves the throwout bearing, throwout bearing it's self and the hydraulic parts of the clutch are the only other things you can check. Have someone else push in the clutch in and watch the slave cylinder, it should move out about and inch, if that doesn't happen replace the clutch slave and master cylinders. I've also had the clutch arm come of the pivot or shift on the shaft so it pivots in the wrong spot. lastly you should check the height of the throwout bearing from where the clutch arm fingers touch the throwout bearing to the front of the throwout bearing and compare that with the old one don't just use the overall height of the bearing that has also bit me before.
If anyone can think of anything else please chime in.

Yes, I had at first thought that the issue was the slave cylinder and replaced it with a new one. I then realized after replacing it and bleeding the system that the clutch fork was pushed all of the way back. That was when I pulled the transmission out again, removed the clutch and re-aligned it, with the thinking that maybe I had installed something wrong. But after re-installing the transmission last night it was still the same way. Let me ask this question, does the throw out bearing "lock" into the fingers of the clutch housing? Or does it just ride on the face?

I had an issue that sounds very similar when I did the clutch on my FB. I ended up having the pressure plate backwards...doh. Installed it the correct way and the issue went away. I ended up taking my trans out multiple times until I figured it out.
Clutch engagement was just fine before you replaced it?

Justin is right the springs on the pressure plate should be facing out away from the engine.
The throwout bearing usually attaches to the clutch fork that is attached to the transmission bell housing which pushes the throwout bearing against the fingers on the pressure plate.

The throwout bearing just rides on the face of the fingers. It doesn't lock onto them. The bearing is clipped onto the clutch fork.
