    Very nice job repairing it Rick. What is the GM part number for this switch?

    That sensor isn't anything fancy. It is simply a temp controlled on/off switch. I expect you need to find one with similar switching temp and it would work. Later cars used lots of them for emissions controls mounted on the intakes and also on the thermostat housing. A little research should find one that would work right.

    Gary, you are correct, but the difficulty is finding a single pole switch AC-93B.

    Rick is right. My tab broke off just like yours did Rick. I still have it. I actually found a two spade switch and used the one side of the switch that was close to the spec of the original. Good luck finding a new one. This has to be the single most difficult part to find for a 1974 z28 with 4 speed.
