I see dead clutch pedals! II

After learning how to do it in the junkyard car, I decided it was time to replace the master cylinder in my convertible. I can't say I am looking forward to remove the center console and knee panel just to get to it.

As I stuck my face on the floor and looked under the knee board, I noticed there was this piece of foam-backed cardboard covering the top of the pedals.
I tried to carefully remove it but it did not come out as nicely as I would. But out it went.
Time to look up again. What do I see? There are the pedals and the master cylinder in all their glory! I stuck my hand there and found out I could reach them all without having to take all those parts I did in the 900 in the junkyard. Not bad at all.

Am I annoyed that I spent all that time in the junkyard for nothing? Not really. I am actually glad because I now feel I learned a better mousetrap. So, time to get busy!
First I disconnected the rubber hose that goes from the brake fluid reservoir to the master cylinder. To avoid it dripping all over the place I just turned it so the end that was connected to the clutch master cylinder ended up above the reservoir.
Before unbolting the master cylinder, I chose to loose the line that goes to the slave cylinder. This way, I take care of all the connections in the engine bay. I broke the line loose using my 13mm crowsfoot wrench because rounding off the nut in the end of the line would spoil my day.
Then it was a matter of turning loose the nut with a normal wrench. Not very fun because my hand had to be shoved stuck in there and then I could only turn a little bit at a time. Every so often I had to take my hand out and massage it. But loose it came.
Next on the list was to remove the little bracket that holds the clutch line against the left shock tower.
Reason for that is so we have a bit of play and be able to remove the line from the back of the master cylinder. Just to be on the safe side I placed a rag under it so it would not eat up the paint.
Now that is taken care of, it is time to remove the master cylinder. It really was just a matter of removing the two bolts that hold it to the firewall, and separating it from the clutch pedal (a clip holds a pin that goes through it and through the pedal). Here I am putting the new master cylinder in place. The picture would look the same for the old one.
After that it is a matter of connecting the rubber line back to the master cylinder.
And the metal line that feed the slave cylinder. After all that is done, we need to bleed the clutch system. I would like to have some help doing that but it feels like I will be on my own. So, I need to find a way to do it alone. But that is for another episode...
