I decided to install an Andair selector rather than the Europa supplied unit. I originally fitted the selector to the position described by Europa, but later in to the build i decided to move the selector to the central tunnel arm rest.

Moving the selector required the installation of an extension drive and a plywood support. The support was glassed on both sides and then floxed and glassed in to position.

The valve was then placed on the underside of the support. The following images shows the installation.
