Buick Fan Switch?

I've done the reading, and I want to purchase a new fan switch.

I have a 87 Z28 with the LG4, non-CC. So I don't need to worry about how low I go since my carb will squirt the same fuel regardless right?

With that in mind, what's the lowest fan switch I can get (And it's turn on/off temp's)? I don't want to spend $50-60 on an adjustable one, I'm hoping for a stock replacement.

Also - if you have the part numbers that would be helpful.

Ive heard the GN switch will work and is lower BUT I could be wrong. Let someone verify that before you go buy one,.

the GN switch is lower, not much though, mine turns on at 220-225

here is an aftermarket one for $19 though

you only need the switch, not the harness(only vettes)
