GM part number for coolant temp sensor Cutlass???

[HAFROD]

I'm looking for a GM AC Delco coolant temperature sensor for my 78 Cutlass Salon with gauges (NOT idiot light). I've tried two non AC Delco from my local parts store and they are not working correctly. Does anyone have a way to get me the part number for AC Delco?

Are they the same as Monte Carlo with gauges? The sensor only takes one wire hook up

if I look up a 78 Salon w/ 305 on RockAuto I get this:

G1852
12334860
1513321

looks like the right animal but I went thru the same thing on the cutlass, about 3 different ones until I found the right one.
