pretty easy job, loosen the hydraulic line fitting first with a flare nut wrench, then the 2 mounting bolts, then the hydraulic line, with the slave cylinder unmounted you can remove the hydraulic line without bending it
Slap in a new one, reverse steps as above, then attach a clear plastic tubing to the bleeder valve nipple, the other end in a plastic 12 oz clear soda bottle. Then with a wrench open it up about 1/4 turn or more.
Then have a buddy press on the clutch pedal and hold it down, then you tighten the bleeder valve again, buddy raises clutch pedal, repeat until no air bubbles in the system. Better yet, repeat until all the brake fluid is yellow and no air in the system. Top off the clutch master cylinder about every 6 or so clutch pedal presses.
Access to the clutch slave is easier if you drive the truck up on ramps.
