Another first from Scott Drake, Upper Radiator Insulators for 3 and 4 row radiators. You no longer have to modify stock, 2-row radiator insulators to install larger radiators. These 1967-70 Upper Radiator Insulators are made from high-quality EPDM rubber and are now available in a 3-row or 4-row size. They are a perfect fit to our Upper Radiator Brackets (C7ZZ-8A193-A & -S). 1968-70 vehicles do not require larger lower insulators. 1967 vehicles must run 1968-and-up lower brackets and insulators.
