Slant Six Manifold Flared Nuts

Thanks Guys. I found the flared bolt on McMaster Carr. I realized that I also have a broken washer, like the one to the right on the photo Cuda416 attached. Also, does anyone know where to get a radiator for a slant 6?? The bolts spaces are 21 1/4" side to side and 11 1/2 inches top to bottom bolts. I tried Classic Industries with no luck.
