Can anyone tell me what is the correct temperature sender for a 1968 olds 455 with a temperature gauge? Preferably from BWD.
I've went in twice now and they have given me a WT331 and a different one but they both appear to be for a light because they are switches, so they are not a temperature gauge. I even checked them with an ohm meter and they were off for the entire time till hot enough.

I found a BWD WT733 that claims it is for a gauge and will fit, can anyone confirm if that will work (has the correct resistance specifications) with a 1968 Cutlass temperature gauge?

 

GM PN # 546702 if that helps.
