Disco 1 Rivet or screw?

Hi folks,

Finally (after about 6 months!) putting my disco back together, but i have forgotten what fixings i took out of part of my rear quarter panel (fixings number 11).

I seem to remember having to drill them out, like rivets, but the workshop manual says they are three countersunk self tapping screws.

Any chance one of you guys can look at your disco and let me know?

Thanks!
