Thanks for the replies guys (& to the PM's I recieved as well).
I started off by trying to remove the clevis pins from the wok to pull just the clutch arm out, no go.
So I ended up pulling the wok off and drifting the clevis pins out (took about 4 good hits to remove both of them - I had no chance while it was in the car
My parts list for lunch today is as follows:
new slave cylinder (leaking - dust cap full of thick brown goo)
plunger (very worn indent from lever arm)
lever arm (almost no ball left on one side)
upper and lower clevis pins (substantial groove worked into both of them)
new slave push rod (old one wasn't looking too good after bathing in brake fluid)
more brake fluid to top up the master cylinder as some of it escaped when I was pulling things apart
At the moment I am just hoping that I don't damage the throwout bearing trying to get it off of the old plunger as it is still in good condition.
I'm pretty sure this will fix my problem. If it doesn't I'll keep chucking new parts at it until it does
