FWIW, there is no such thing as SS gauges after 1965. Gauges (and tach) were optional with any V8 in most Malibu models ( optional even for SS396 or SS-optioned Chevelles). Don't know if typical parts stores might have them but just ask for the appropriate sender for the gauge as opposed to the warning lamp.
My parts book shows #546702 for the water temp switch (69-72 All w/gauges) and #6461928 for oil pressure (69 Chevelle only). Particular engine size is not relevant.
