Still haven't figured out how to run the fans. The donor bus used hydraulic fans but Mike would like to convert them to mechanical off the engine. He says they are much more efficient. As far as why the conversion to side vs. rear radiator, I'm not sure. When @Relic and I first came up with the plan, that was it. The donor bus had the radiator and intercooler on the side and it made sense.

Picture of the new air bags, replacing all 8.
