There is a dimple in the upper radiator hose in my '72 Skylark GS 455 convertible, so I started looking for a replacement. I can't find one. Year One only has the upper hose for a 72 GS350 or 70 GS 455? Does one of the earlier hoses interchange? Or does someone know where I can buy a correct GM style upper radiator hose? Help!!! Thanks for your help in advance, Morris
