I hate to be fussy, but I'd be hesitant about starting to state that these 2 pairs of side rivets are different sizes as verified fact at this point. I don't think I'm alone (or at least it sounds like
lonepigeon might agree with me based on
this post here) in suggesting that the lighting and angle of view in the below photo are potentially giving an inaccurate impression of the comparative size of the rivets. There's enough wiggle room in interpretation of photographs to account for a perceived difference in size. My gut is still saying that all these rivets, both on the side and holding in the D-ring, are all the same size... I just thought it might be worthwhile to mention before people start etching these ideas in stone as absolute fact!
