I found to day the jap manual wrx gear boxes have a extension cable for the speedo cable about 130mm long .With this you can get an auto cable & clip it together making it reach the back of the speedo with a lifted liberty ect .

just thought I let you all know , seagull

All the EJ boxes have a small part on the bottom that separates, not just the JDM turbos.
So you replaced the manual upper part with an auto one?

Not all the EJ boxes, there is quite a few that have electronic sendors. But yes, a lot of the early AJ boxes had it.
