This is a new pair of D-port standard exhaust manifolds.  These have been reproduced exactly like the originals, but without date codes.  Has correct part numbers 9779032 & 9779328 cast on them.  The passenger side has the correct functional heat riser (heat riser spring is available separately).  Includes a left & a right exhaust manifold. These are correct for 64-68 GTO LeMans Tempest.  Although newer year manifolds did not have heat riser, they can be used on newer years.  Incudes as shown.
