Here is the same area on the non-1970 door. Compare it to the picture above.

Again, you can see where I made the round cat whiskar holes oval shaped to accept the clips on my 1970 cat whiskar set. My cat whiskar set is reproduction, and doesn't have a clip in one of the factory locations, so I didn't bother to make the unused hole oval shaped.

There is an oval hole for an extra window guide that was added after 1970.

There are also some other extra holes, and part of the door is actually stamped a different shape.
