904 disassembly help needed

I don't know what was put into the valve body. I have another one that is stock that I will pull apart and clean out real well. I bought a TF-2 to put in it so at least I will know what is in it. I Along with the master rebuild kit, I also got a new rear band, and a spring and roller kit for the overrunning clutch. (One of the springs was broken.)

Starting from scratch is always a good plan
