350/SM465 Clutch Question
 
Was getting some rattling noises coming from my bell housing area. Yesterday I snaked in a camera and it looks like my clutch release bearing and fork are worn out. Can someone confirm this?

Video of me wiggling the shift fork and seeing play in bearing.

I was also getting quite a bit of clutch chatter when releasing clutch from a stop, especially on a grade or pulling a load, even starting in granny low.

So it's probably time to replace the clutch anyways.

Here is the parts list I'm planning on ordering. Anything I'm forgetting or should get instead?

- Clutch Kit (SACHS K190902HD) - Heavy Duty 12" clutch [$116.79]
- Flywheel (SACHS NFW1007) - Solid Flywheel; 12" Clutch/Diaphragm Cover [$77.79]
- Clutch Fork (ATP ZA100) [$13.58]
- Pressure Plate Bolt Kit (ARP High Performance Series Pressure Plate Bolt Kits 130-2201) [$24.99]
- Flywheel Bolts (ARP Pro Series Flywheel Bolts 200-2802) [$23.99]

From what I can tell, those bolt kits should work right? The flywheel set is for 2 pc rear main which my 350 is. I did order some new clutch pedal stuff like new springs, bushings, etc. as well. Anything I'm forgetting? Anything else I should do while transmission is dropped?

Looks kinda normal to me. Is the new pressure plate a 3 finger like this one or a diaphragm plate? The diaphragm will be easier on the linkage and your knee with the same amount of clamping force and will be a smoother engagement. The only thing that bothers me a little is at the beginning of the video there was the side to side movement of the bearing on the nose cone. You can take a better look when it comes apart to determine whether or not the bearing retainer needs to be replaced also
