A heavy duty one from the parts store should be fine. Or if you want a Motorcraft replacement: http://www.latemodelrestoration.com/item/LRS-8616A/86-93-Ford-Mustang-50L-Motorcraft-Fan-Clutch

I paid less than that for a Fox Mustang police interceptor fan clutch about 5 years ago. I don't think they are being made anymore however.
