When I had a 70 Hornet a couple of years ago I swapped in a radiator from a 73 Gremlin. Fit fine, no problems. So I looked up a 73 Gremlin on the autozone web site. They list a Transpro part number 433403. It's a two row, 16 7/8" x 24 1/4" x 1 1/4" core size. You may also want to look at radiators for a Spirit. Part numbers 433578 and 433579 are two core and three core respectively for an 83 Spirit. I would think these could easily be adapted to your Hornet.
