All these short fan clutch topics...
Made me think that I had a factory Mopar skinny viscous clutch/fan combo somewhere, so I went looking for it. Sure enough, this is from a 1980 slant six Diplomat with A/C . The fan is 18", the clutch is 2.90" flange to front edge of thermo coil, and the fan blades are about 2.70" inches thick. That car had only 80K so I'm sure it was the original.
