Hello, I just had an RnD alum radiator shipped to me for a customers '73 IH pickup I am working on. The install went just fine, and overall appears to be a very good quality product. However, both necks on the radiator are about 1/4 inch smaller in diameter than the original. I could probably over clamp, or double clamp the hoses and "make it work" but it just doesnt seem right. Any suggestions?
