The big floppy metal rod is the gear change. The two tubes which don't move are the radiator flow and return.
I managed to change the rear cable with one of the radiator tubes out, and the engine and gearbox out, to give clear access to the Y of the chassis where the outer cable goes into a U.
Once you get the C clips off the outers where they are holding the U into the Y, once you take out the split pins and spigot pins from the back of the drums, the whole cable will go into the black hole, and you can then get the U clamp and cable out through the hole in the top below the rectangular pad.
Then you can get the U clamp off with a metal chisel to put on the new cable.
i have only been leaking a little bit so far- just reopening the original wounds.
got the spring off the intermediate cable, removed the adjusting nuts, and freed the intermediate cable.
managed the cable clip removals inside, so the cable should pull out "through the slit in the rear of the chassis", after removing the "horseshoe"(haven't figured that out yet).
what slit?
this started as an inspection kinda thing. starting to fall down the rabbit hole a bit, mabe.
gonna have a harp and give it another coat of looking at.......

managed to get that horseshoe off. as bda described, it was not easy to open the crimped thing, especially inside the chassis, and i only bruised my forearms getting them both down the hole and holding and prying, and will look bad for weeks(you know- what happened to you?).
the slit was cleverly hidden with a piece of tape.
the cable is out.
a side benefit is that i pulled the dud choke cable and the heat control cable(reuseable).
