Engine Mounts

mounts are the same, only difference comes in 66, when they were changed from a cast iron body mount to a 2 piece stamping. the stamping is a bit stronger,but the engine will sit about 1" higher in the chassis.(good if your car is lowered, and you run the risk of headers scraping the ground)btw, the cast mounts, and the stamped use different isolators... cast will have `1 stud through the bracket, and the stamping uses a 5/16 bolt through both the bracket and isolator.
