Putting together a 413 for our '62 300 Sport. I have no faith in the local Napa store and most every other "real" parts store has gone out of business. The Napa store ordered me a new temperature sending unit for a '64 300 with a gauge, though its too small. Does anyone know a part number for the correct sending unit? Also. Where the oil sending unit goes, there is also a plug that blocks an oil passage. Does anyone know the specs for the oil passage as I need to buy a new plug? Thanks!
