Issues with 360 engine mounts

They sold you 2 pass side mounts
I agree that I have two of the same side. But the one I have on the drivers side wouldn’t work on the passenger side because one tab only has one hole, plus the holes for the insulator would be to the rear of the engine instead of the front. I feel like I have two drivers side mounts, just not for a 360. That’s why I had to drill new holes on the one I put on the passenger side.
So after seeing what I have, what is your suggestion to make what I have work? I’m thinking slot the holes that the insulators bolt to so it can move up enough so they sit flat on the k frame
