63-66 A body V8 drop center link

I have a late model slant six in a 73 Dart. I did not change the oil pan and pick up from the 66. Drag link drags acrooss the pan. I shimmed the motor with 1/4" plates. The motor mounts squeezed and the oil pan still rest on center link. Don't want to hammer the oil pan for clearance. Doh !!!!!
