I purchased an aluminum radiator 4 core for My 1969 Impala SS427 without electric fans. It came as a 24 wide, total 28 wide which includes the side brackets. My fan shroud is 26 inches wide. I had to make side covers to mount the shroud. Also; the radiator is shorter by 2 inches. The tanks hit the radiator support , so I had to add 1/2 inch of shims. The pictures show the finished product. A little more cosmetics and a special spacer will be made. 7 inch Anson slots with 245 front and 275 60 rear. NICK L72
