The original (I think) fan clutch in my 70 Charger R/T 440 w A/C just seized up and started to howl like mad. The car is stock and I'm just looking for as close as possible parts store replacement but when I look at Napa and Oreily they have a ton of different ones that supposedly fit. Can anyone recommend a specific one from either store that will functionally be about the equivalent to the stock original one.
