The Lower Radiator hose located on the Passengers side is with out doubt correct for the 67-69 Mustang Small block.
So, the "Newer" motor has been fitted with the early water pump--GOOD.
Next, the Head bolts are 3/8" GREAT, it has the early heads as well.
This combination will accept, bolt on, the Factory Pump brackets for the small block.
Aluminum bracket, a C7AA, the flat steel will be the one with hole, the one without hole is a 69 351W.
