Default Clutch Release Bearing

I've got a problem with my clutch all of a sudden. My car is an 89 6 speed.

The previous owner replaced the clutch with a LuK kit 18 months ago, and I've covered around 10k miles since. I went to drive it today and with the clutch pedal depressed, there's a whinning/grumbling sound. To me this suggests the throw out bearing has failed? It happens with the pedal all the way depressed, I can soften the noise if I raise it a little. Reading online it sounds like the quality of the new bearings in the kits is not up to that of the originals. Is there a source for a quality bearing? And given that I'm going to have to pay a garage to do the work, would you replace the clutch, even though it only has around 10k on it. I see Rock Auto sell an AC Delco one separately.

I've got a space booked at a car show tomorrow, will I do any damage taking my car there? I have a daily shed otherwise.

FWIW I'm in the UK and have only ever driven manual cars, so I would like to rule out my technique!

Thanks in advance.

Can you use a trailer for the show, is it far away, a bad throwout may damage pressure plate fingers.

If you have to lift the pedal to get the noise to stop then it wasn't right to begin with. Throw-out bearings should not be spinning with the pedal at rest. If they are, they won't last very long.
