383 sits crooked in engine bay

The upper photo is of my K-frame. It looks to me, as if there was an ear on top of the forward portion of the driver's mount, the engine would sit level, as that would put it the same height as the passenger side. Instead, the bolt that goes through the engine mount also goes through the holes in the lower portion of the mount, putting the engine in a crooked position. The other pictures are of the mounts I have, as installed on the engine. Maybe, I should just fabricate and weld an extension, to match the rear "ear" of the driver's mount?
