How to replace a hydralic clutch resovior

I have a 89 F150. My hydralic clutch seems to be leaking quite a bit, been adding fluid for a while. I've checked it out and it happens over time, but I'm a fraid this is going to wreak my clutch plate if I don't get it fixed soon. Anyway looking at it I don't see any bolts on the firewall side. Is this going to be hard to get to under the dash. Has anyone fixed a leaky clutch before?

check under the dash where the clutch pushrod goes through the firewall. I know on older ones that's where you'll find the nuts to remove. Check your slave cylinder also for leaks. Replacement for the master cylinder is easier if someone holds the new one in place while you start the nuts on.

I'll check there for those bolts. And double check that slave.
