Help interpreting instructions Section 24-02 step 3

Last sentence on this step "Machine countersink the two holes on the inside lower center face of the roll bar that will get flush blind rivets. See Figure 1."

I've countersunk all the outer flange holes on the roll bar, but that this last sentence seems to be referring to two additional holes that I can't seem to locate or understand. Maybe its been too long of a day in the shop.

Anything someone can advise I am missing here?

thanks,

They are the 2 rivets marked CS4-4 on drawing 1 with the arrows pointing to them. Underside of roll bar I believe.

I believe D&M Dan is correct. I remember looking for those holes for quite a while before finding them. I think it might be part of an eye test!

I have a lot of pictures of that page:

Figured it out

Thanks everyone. Will order 3D glasses and a magnifying glass next time. I think I figured it out.
