I didn`t go back and look, but the first pic looked like the fan was on backward to me, the second pic looked right. If u have the same width between the frame rails, and u should, u could go to an alum. crossflow 28x 19 . w/ 1 1/4" or 1 1/2 '' tubes. I wish I`d gone w/ 1 1/2" on mine, instead of 1 1/4' . I couldn`t get a 16" elec fan in front , and had to go to a 15", and put it and the trans cooler as far away from the rad.as I could so not to impede air flow any more than necessary. I even put hood vents in because of underhood heat. MY raised port heads put the headers way up to where it even melts the valvecover gaskets. I might gain a little by cutting the cradle out to be open in front of the side tanks, but haven`t needed to so far. " If anyone needs a new 3000 cfm chrome elec fan , I have one."-----------hope this helps, cooling big h.p. is a lot harder in these little engine bays.
