Now it gets interesting. Extracting the first bush is a test unless you use a press to push them both out the same way. This time I thought I'd try sawing down the length, so made up a special hacksaw from two strips of aluminium with a limited depth. This worked well enough, but that first bush still put up a fight.

For the second bush I used Mulfab's tool, and it came out easily........
