Need replacement clutch kit for '94

[Rusty]

So for the past while I've occasionally had a bit of a screeching/whistling noise when the clutch pedal is depressed (assuming the throwout bearing), and the last few weeks I've started experiencing a "shiver" when I'm shifting and the clutch is engaging. So I'm planning on a clutch replacement and would appreciate advice on where to find one that's EXACTLY a stock replacement for a '94. Based on what I've read it sounds like some of the clutch kits advertised as a replacement are actually slightly different, so I'd appreciate advice on where such a thing can be found?

Also, I'm not really clear on whether it's necessary/advisable to replace the flywheel at the same time? Thoughts on this point are also appreciated!
