Fan assembly on 92 Eagle

Is it possible to substitute/insert other car fans in this assembly with out buying the factory 2 fan system?
Parts are of coarse espensive ;and I'm trying to avoid dealer prices if I can.

Yes, it is possible, but you will most likely need to drill new mount points, and cut/rewire the fan wires. I'd suggest a Chevy electric fan, they seem the easiest to swap. Or if you have a boneyard in your area, try to find an eagle, or a Dodge Monaco of the similar year. The Monaco's share almost all the mechanical parts with the Eagle.
