Replacing the clutch master and slave on a 1500 Midget is a straight forward job. Disconnect, unbolt, remove. Sounds simple, lol. If you jack up the car and place it securely on jack stands, you can get underneath to remove the slave cylinder pinch bolt. With the pinch bolt removed, the slave will slide out of the bell housing, it takes some wiggling, but it does slide out. One clevis pin and two bolts hold the master to the pedal box. You can disconnect the hose at either end to remove it all from the car. There are only a couple of things that I did to make the installation and bleeding job a lot easier. Because the bleed port on the slave is lower than inlet connection, it is almost impossible to bleed the clutch. Where the clutch hose runs down through the hole in the battery box, I enlarged the hole so as to fit the slave through the battery box with it connected to the hose and master. I then proceeded to bench bleed the master and slave cyliner. I used a spare push rod in the slave and wrapped a large rubber band to provide some back force. I then bleed the slave while operating the master manually. Once the system was bled, I installed the master, run the slave down through the enlarge hole in the battery box and installed the slave. Don't forget to cromet the new hole to protect the hose. I don't have any problem bleeding the clutch system either. If I need to bleed my clutch, I remove the slave, slide it out through the battery box, suspend it from something to make the slave and vent port the highest point in the system and bleed it.
Just one way of doing it.
