I had the same problem with my 36. The issue I had was because I had taken my radiator to a radiator shop to get it re cored. You may have a completely different issue, but I thought this story might help. When I reinstalled the radiator after the shop re-cored my radiator, the hood no longer fit properly. I returned it to the shop several times, even with a separate old 1936 radiator that fit properly in my 36 to use as a template. It still came back with the same problem. After several returns to the shop, the radiator shop said I could keep the radiator with the new core. They gave me my money back and suggested I find another shop. I took it to a different radiator shop in town that also had a reputation of being able to do quality work on older radiators. The owner’s son now runs the business and said he preferred not to work on old car radiators because the money is working on and swapping out, radiators on newer vehicles, but he would try to correct the problem. He was unsuccessful in two attempts to correct the problem with the radiator. I decided not to continue with another shop. Eventually I purchased a new radiator from BrassWorks. There was a long wait to get it, it wasn’t inexpensive, but it dropped right in, all the sheet metal lines up correctly, and it works well. You may have a radiator shop in your vicinity that can fix your radiator. The radiator’s height and the tank’s angle and relative position on the core is key to having the sheet metal fit properly. If all else fails, and you can live with an incorrect radiator, Brassworks is an option. Good luck!
