Standard 73 model water pump. Aluminum. pass side inlet. Stock 73 318 fan and clutch (A/C if it matters). Radiator out of the 73 is a 26" 2 row with shroud. Radiator is shot. Trying to find a radiator that will fit a 73 318 in a 69 Barracuda /6. Eventually a 340 will be there so I want the radiator to be handle at least that.
