If indeed your clutch cylinder is shot, an alternative to a brand new one is to send your old clutch or slave cylinder off to Apple Hydraulics and see if it can be sleeved. What you will end up with is better than a new, unsleeved unit.

Historically the clutch master cylinder is made of aluminum. No liner(or sleeve) on the bore surface. It is susceptible to corrosion.
I would presume that apple hydraulics, when they sleeve, the cylinder, apply a different material liner. i.e. copper, brass, steel, iron. dunno as I haven't used their services.
Why, the clutch master is a pretty common part that all of the Monster List suppliers can provide at a very reasonable price. Even Pegasus and other race suppliers have it in stock, it is so common that alot of the Formula racers use the same cylinder.
To help prevent this happening again in the future, remember that the Dot3/Dot4 brake fluid is hygroscopic,i.e., it absorbs moisture from the atmosphere(and car washes, hood washes, etc.) It needs to be replaced(flushed, if you will) at least every two years. Or completely replace it with Silicone brake fluid(Dot5). Not that hard, and a lot more effective to remove the old in the clutch system, as you've got pretty straight hydraulic pathways.

I said that a hydraulic slave or master cylinder that is in good condition and can be sleeved is better than a new unit that comes from the manufacturer not sleeved.
