New Abbott Cable-x box. Allows you to use cable speedo with late model T56 or other trans without provision for cable hook-up.
$340 new, $225 shipped. Installed but never actually run. New in August of 2012 so it's the latest version.

Bought it last year but have decided to go for an electronic speedo conversion. Just looking to get back what I paid for it.
