New in original Mopar box - NOS Mopar part number 4287154.  This fits various models of Dodge trucks from 1988–1993 equipped with 3.9 L (6-cyl), 5.2 L (V8) and 5.9 L (V8) engines.  I believe it will fit the 1989 Shelby Dakota with the 5.2L V8 engine but please do your own research before committing to purchase as we do not accept returns.
