If your clutch master cylinder goes out, the new one comes in two parts, the cylinder and the rod to the pedal. After you install the cylinder from the outside, you then push the rod into the plunger and it locks into place. Don't make the mistake of doing this before it's been bled, like I did. At that point it's best to pull the fluid line plum out (not a piece of cake but can be done. I had no help here when doing mine and tied a wire to the master cylinder and connected transmission tube, hooked an old door spring to it and tied the tail high on the hood to put upward tug on the line, then got got underneath and fed it through)
Then anchor high enough it doesnt reach the ground, fill the reservoir , and wiggle those lines all around untill you don't hear any more bubble. Put the cap back on the reservoir and feed it all back thru pre-bled.
Wish I had known that before snapping that plunge rod back in, cause after that the only way to get it out was pull the brake booster cylinder out the way, allowing the clutch master cylinder to be removed in an upward direction
I also like the method Blackwidow suggested, sounds good to me, wish I had known it then
