Need help on 165 degree temp switch

[plymouthtomas]

Hello to ALL

My question is, I put a 440 eng in my 46 ply coupe I'm have the orignal raditor in the car, it been clean out and service, I have two electric fans I would like one fan to come on at 165 or 170 degrees and the other fan to come on at 180 to 185

I found the 180 to 185 temp switchs all day long, but the 165 ot 170 temp switch no where to be found

The 440 eng is great shape, I would make sure it don't get hot

I'm running temp switch relays 12v neg to turn it on

thanks
