Steele Rubber, $30.00 plus, per set, I posted this and you need 2 sets, I sprung for them for my 66, and they are somewhat difficult to install. Soaking in HOT water helps and when you put the radiator in you need to work them into place. A trick to do for the top plate is,if you have used ones with the tabs broken off grind that area flat and get some small rubber bumpers with about the same looking tab and grind off the bumper to very thin and install in the top plate, put the used isolator over the radiator tank and tighten the bolts and it looks like OEM.
