Carl,
It would require major modifications to fabricate the mounts to support the radiator weight, and the extra width. You would also have to fabricate mounts that were strong enough to support the 60 HP hydraulic cooling fan. Then you would need to fabricate and reroute the radiator hose system, design and install a hydraulic fan control system as well as the needed changes to the hydraulic system to operate the fan, modify the CAC system, and fabricate a fan shroud. The cost would run into the thousands in parts alone before you add in the labor and the cost of the new radiator. In short, I would trade coaches if I was trying to go from a rear radiator to a side radiator, and I could do all of the work myself, but the prohibitive parts cost alone would not make sense to me.
