MOTOR MOUNTS

With some free time, I'm building a 360 for my '80 F body. Presently its a 318. Has the factory motor mounts. The 360 should be making abot 450 HP. Looked at Rock auto for new mounts, not just the insulators. They don't show any difference between a 318 and 360. I thought the drivers side mount is different. Whose right?
