hi mine were solid too, my car had 38 k on it and is a daily drive......... grab the pin in the middle with some grips and waggle up and down , tap the end with a punch to move it a bit then a thin piece of emery cloth around the pin and pull it back and forth until the pin is clear of rust, tap it back in and out a bit and keep cleaning it with the emery cloth until the pin is the size of the hole and it should just pull or tap out. The hole for the pin is tight so a little bit of rust will stop it coming out, you can put as much penetrating fluid on it as you like and it will not free it off its all down to the rust on the pin . After I had done one the rest were dead easy its a nack of doing it and mine were really rusted solid .
