Are these the wrong swap mounts for a Magnum?

UPDATE: I contacted Chris at Schumacher and told him about my screwup. I offered to send the kit back for an exchange and pay the shipping to get the right one to me. To my surprise he not only told he'd be sending me the correct driver's side mount without charging me, he didn't even ask me to send the wrong piece back to him. I'm going to return it anyway, but it's nice to see such good customer service still exists, especially when it's the customer that made the mistake.

Here's the correct (273/318/5.2) mount
