IIRC, the Ver 4 center console was more angular. The Ver 5/6 are slightly curvy. I'd like to know if the center consoles are interchangeable between models (specifically Ver 4 and 6). The current WRX has a really nice aluminum STi gear shift trim available that will not fit the Ver 5/6 but it might fit the Ver 4. Any help and additional pics would be appreciated. Thank you.
