Small block engine mount question

Hey all, I have a tired old 1971 la318 in my 66 Dart, and I’m swapping it for a much fresher 1974 la318. I’m just about ready to do the swap, but the mounts look slightly different on each. Am I crazy, or is that normal? The 74 came out of a 69 Dart, and the mounts appear to sit much closer to the block than the one currently in my 66.

I couldn’t get clear pictures of the 66, it was too dark, but if needed I can try tomorrow.

If this is all normal and fine, can I just swap engine mounts from one block to another?

Thanks!
