67 Dart cooling issues
Get a sheet metal shop to fabricate a "box" the size you need. Then remove the fan, install the box, cutting a small clearance hole if necessary to get it in. Carefully measure for the center of the pump
Then just make a compass (two sheetrock screws or nails in a light board) so you can scribe the fan diameter + say, 1" clearance for the fan. If you had to cut a clearance hole, you can establish a center by screwing a scrap board across the inside of the hole.
There was a thread here recently someone made their own out of aluminum, pop - riveted the corners
HERE we go!!

The only improvement I would make in this project is to make an extended skirt, IE a circular add on around the fan. This is also easy to make. All you need is a strip of metal, which you can have the shop cut, long enough to go all the way around the opening. Some shops have a mechanical "notcher" which will make nice even tabs down one side. You bend 1/2 of them over, insert the skirt, and bend the other half of the tabs over. Then screw/ solder/ braze/ etc/ rivet the thing in place
I could not find a homebuilt one, but a skirt like this:
You can buy hand operated notchers, or if you are patient, you can make them with snips
