Hey If you want to was money go ahead but I am telling you they will not work. The steel mounts pictured above will sit your motor to low and the early rubber isolators will not bolt to them directly. The steel mounts you need are taller then the ones pictured. If you can not find a used set I would spend the money and buy the Schumacher. Those pictured are for an E Body. Below is my 65 Valiant with a 372 Stoker motor and chassie Headers, trust me I know what will work and what wont work. You need the correct motor mounts.
I will double check to see if I have set.
