I am very sure that this question has been asked before, probably many times.  However I am not very good with the archive search.  My question is about the coolant temperature sending unit and the oil pressure sending unit ports near the oil filter and the heater hose outlet.  Does anyone know the size and type of threads these two ports are?  If these ports are not utilized they will need to be plugged.  I am not sure but I believe they are a BSP thread?  Where would you find odd fittings to plug these ports?
