It's really not that hard to replace the clutch master cylinder. You have to undo a bunch of vacume hoses next to the brake master cylinder and reservoir (both brakes and clutch use the same reservoir) to get at it. Like i said before, the back mounting nut is hard to get at if you have big hands, so have a good socket set with various swivels and extentions. Also would be good to have a flare wrench set for removing the hydraulic line from the master cylinder to avoid stripping it. Off the top of my head, here's how to do it.

Undo the hoses next to the brake reservoir to gain access to the master cylinder below that. Use a small set of vise grips to close off the hose going from the reservoir to the master cylinder.

Inside the car, undo the clip holding the master cylinder to the clutch pedal. ( I needed a socket snake to get at some of the back mounting nuts for the cover that has to be removed).

Back under the hood, using a flare wrench, undo the hydraulic line coming out of the front of the master cylinder. Then remove both mounting nuts holding the master cylinder on the firewall. That back one was hard to get at for my car with A/C. Remove the hydraulic line in (that you clamped off earlier). You should then be able to remove the master cylinder. It was much harder to get out than to put the new one back in, but installation is just the reverse, be careful to replace the vacume hoses properly.

Then bleed the system, if I do that again, I think I'll buy some sort of bleeder. Manually it seemed like it would never work, but it eventually started pumping.... the next day late.
