If you go with that style radiator Stewart, you need to modify the mounting pad insulators.Aluminum radiators with plastic tanks are more than fine. Make sure you flush the system and maintain it! Use premixed, not tap water mix, ground the core if possible, and enjoy a more modern trouble-free lighter weight radiator that is readily available. If you have a problem with it, you don't need to band-aid it. Most parts stores carry a lifetime warranty on them and have them same day for you.
