This Carburetor Spacer came off a 1969 Mustang 351W 4V engine. The part number suffix is an "E" which means it came with a vehicle with a PCV system (those without a PCV system had a suffix of "A"). This spacer is in excellent shape and you can clearly see the part number on the back side. It can also be used on a nonPCV engine by just blocking off the PCV port on the back of the spacer.
CONDITION DESCRIPTION: (Please read carefully) This spacer is in excellent conditon. It does not have defects or corrosion. It has a small amount of carbon on the underside but will clean up easily. All the gasket mating surfaces are smooth with no defects. I would rate it a 9.8 out of 10. Not a 10 out of 10 because it is used.
