This morning I ordered some new radiator hoses and other cooling system parts for the truck. I got a new radiator cap while I was at it. I ordered some thermostats and gaskets. All of those parts were listed for a Datsun 520 but should fit the 320. I was pleasantly surprised to find a water pump and fan drive explicitly listed for the 320 at RockAuto and ordered those also.
Here are the part numbers, including the model of Datsun truck that those parts were listed under. I ordered most of it from rockauto but did get a couple of parts from Amazon where the total cost including shipping (which was free from Amazon) was lower.
