383 sits crooked in engine bay

Bpught a 73 Dart Sport as a project. Engine was already installed, and had been a running, driving car until the former owner took it all part for paint work. Anyways, the engine was sitting crooked, bolted in place, approximately 1/2 lower on the Driver's side. Looking at the K-frame, on the Driver's side, it makes perfect sense as to why, as I can see that difference. There is a single mounting "ear" at the top rear of the k-frame engine mount, then about a 1/2 to 3/4 " lower, is an opening for a through bolt (front and rear of the same mount), into which, the bolt holding the engine and frame mounts together was installed. Maybe later, I can post a pic of what I am talking about, but I already have the engine out of the car. Any ideas? Wrong K-frame? Wrong engine mounts? how to fix?
