I was given this to sell because they couldn't sell it with the box torn like that. I don't know anything about radiators. I only know that the box says 13221. I copied somebody else's post. There are 2 areas, both pictured, that have around 10 to 20 little sections bent. One on front and one on back. Not on the same section. It's approximately 27.5 inches wide and the metal area is 16 inches tall. It has pipes and screw on things both top and bottom. If you need pictures of these let me know. Thanks!
