Thinking of going clutch factory style radiator cooling fan..

Reminds me of back when many owners were dropping 350s in S10 pickups. here was only one very close clutch available that would work in that application. Very difficult to find too. Rodney @ Adams Auto Parts knew to gather all he could find and got 40 each for them if my memory serves. Of course, that was years ago when close fit electric fans weren't growing on a interweb tree.
If I had to choose today,,, electric fan.
