The cover and ducting on the second picture seems about right, but you don't have to have the air being forced from the front like that, it's ugly IMO. If you just scoop up the air going past the bottom you'll gather plenty, as long as it can only go through the rad. Trying not to repost here, but if the inside looks like that and the outside looks like this
and you've got a hole in the bottom of the spare tire well to let the air into the radiator chamber, you're good to go.
