Cooler Link
Good idea about leaning the radiator back Brent. That will make it much easier to mount the unit. Also getting the hoses out the side. Mine has been there for two years with no damage so far!
Wobly: The coolers are usually rated by GWV size of vehicle. The one I used was for a 20,000 GWV vehicle so is a bit larger then needed. The one you mention is about the same size phsyically as the one I used so it should be fine.
