What's the fluid like in your clutch linkage? When was the last time it was replaced?
Your clutch slippage could be the result of a sticking slave cylinder piston.
If your clutch linkage is ok, then you can pull the clutch cover and remove the springs and pressure plate, and then the drive and friction plates and inspect.
I'd suggest when you pull the plates, lay them in a stack with first plate down so you can reinstall in reverse order. Particularly if you pulled out the judder spring and seat.
It would also help if you had an electronic caliper to measure friction plate thickness.
That would tell you if your friction plates had worn beyond the service limit.
The steel drive plates should be ok unless overheated and warped.
