Here is a photo of my car with the body off from a few years ago. You'll see the radiator on my 1995 vintage Everett-Morrison is vertical. It sits inside a steel frame that secures and cushions the radiator. The steel frame attaches to the chassis frame rails on each side. I don't recall the dimensions of the frame/radiator, but it provides adequate cooling here in the deep south, even at track day events. I believe it's a Griffin brand radiator in one of their stock sizes.
