67 specific manual steering box mounting bolts

here's a question: does the manual box have a recess for the split washer like the power box? or is it just flat, thus the reason for the (seemingly) larger conical washer
I did not look for a recess.

In the first photo in my original post you can see the 67 OEM 6pt and split washer and the 68 OEM 12 point and conical / flat washer.
