Default 57 Vette with Fan Clutch??

Hi there - 57 vette with non stock 350. 57 didn't come with a fan clutch, but I do now have the 5 blade fan and a clutch on the 350. Clutch went out. I am trying to figure out what to replace it with based on these photos. The car overheats now while idling. No issues while driving, just running hot according to the gauges. And after turning off, there's some overflow out the rad overflow tube. Rad is original. Lines have been burped. Thermostat is new and installed correctly. So, this is why I've landed on the fan clutch being bad.

Can you help me ID this clutch, and a replacement? I think it may be a mid 1960s Vette clutch. The auto stores obviously weren't any help. Note the 3 inch mounting vs 3.25.

Have you checked the temp with an IR gun?
