I'm going to mount the radiators in the back of the 715 short box. Plan on mounting them to the rear tipped towards the front. I'll have passenger seating back there also so there will be baffles to direst the air up thru a large opening in the box floor and then out the back. The old rad opening will be home to my hyd winch. I plan on running a tube from the cab cage to the front of the truck on each side of the engine bay to provide support for the winch mounting plate. These tubes will have some sort of dissconnect to allow easy removal for working on the engine. In stead of shortening the front of the truck I think I am just going to slide the axle out a couple inches on the spring pack and use a revised perch with a different locating hole.
