I have an 88 3.9 that i want to put an electric fan on, where could I find one that would fit properly?

 

Honestly therea about 1000 threads on this a million ways to do it. Could go new, used whateber floats your boat. Best advice I can give is do research and do what fits your budgets and needs.

if it were me, I'd get a fan out of a v6 Taurus and let it eat.
