Outer Limits 4x4 Board

I have a 88 patrol swb with 4.2 petrol. At the moment the clutch grabs right at the top of the pedal and it is annoying me. Is there any way to adjust it so it grabs at around the middle of the pedal travel? The clutch is fine, im not experencing any sliping or any other problems?

There's a couple of nuts with locknuts behind the pedal to adjust pedal height and free play.
