Awesome thanks for the links. So last questions, hopefully my pp fingers look ok, and how to check the throw out bearing is good?

Heres the other side. No groove that I can feel.
Bearing feels pretty silky but there is a subtle but definite ‘notch’ every 10 degrees or so.

That PP looks like the orphan child of your whole clutch pack. It looks in good condition, and looks like it's been replaced and hasn't got much wear at all. The lack of finger grooving is the give away. You had to strike it lucky sooner or later
Throw out bearing should be totally smooth with no 'speed bumps', if you know what I mean, and not sound dry when spun. If you've ever spun a brand new bearing, you'll know what perfect is like ... yours should spin a little more freely, but no noise, bumps, or dry sound.

Also, the flywheel bolts typically do not need soaking prior to removal.

Judging by the streak-marks on both the throw-out bearing and the outer portion of the flywheel, the seal failed on the throw-out bearing whose grease then caused all the bluing on the friction surface.

Bluing = VERY hot. I think the slipping, overheating and consequent hot spots came first. The pilot bearing probably wouldn't have spilled it's grease if it wasn't for the heat. Good chance the throwout has also been overheated, which might explain the grabbing you feel when you rotate it ... do you see grease throw from that too?

You have no idea how nice it is to have a compliment about my clutch pack
I had seen the radial grease lines, I guess that makes sense from the PB, although the car has a range of oil leaks, I wondered if one had found its way in to the flywheel . There are no radial lines from the TOB but it does have that slight notchiness so I am going to need to change it, in my quest to make this the most perfect budget OB clutch job, everrrr.
I dont think I can stretch to a Greg special intermediate shaft, but have messaged Mark about the used one he has listed, I presume its good to have been saved from the scrap pile, and hopefully I can get it on the Christmas deal.
Last on the shopping list then is the TOB, the done thing is pressing in a new bearing to the old shell, yes?

NOTE.. Warning make sure to order a throwout bearing that also matches the guide tube and the release arm if any of these parts dont match then the whole assembly is toast.
That said you might be able to save your throwout bearing by injecting grease into it, this will take some careful inspection to see if you can drill a small hole into the bearing side seal then inject some hi temp wheel bearing grease.
NOTE make sure to get the porsche spline lube, Roger sells it, its dark brown in color and very stringy when placed on your fingers if you get lube that has metallic particles then this is not the grease I am speaking of.
Replace the pilot bearing
