FWIW, so far I've had success with dual fans from a 97 Cutlass with the V6 (same car as the Malibu from same year). It's almost the exact same dimensions as the Ramchargers fans. I've had 2 sets of the Dodge fans crap out on my after less than 2 years DD service each (assuming they are the same as the Ramchargers unit).
I've also read that a Taurus single (mid 90's 3.8 v6) is a good fan that fits.
