Pics are worthless for telling the difference in four inches to five, unless you have scaleable eyes. And, all you have proven is that there are a million and one handlebars out there, I'm still telling you a million fit them. Not literally of course but more than you can count.
Having measurements is worthless to you if like you seem to say they were supposed to be 5" yet they weren't. No way to address that other than having part in hand my friend.
If looking to replicate what the OP here was doing then look at the typical bar called 'superbike' or similar name. Not a brand, rather a type, they are shorter than OEM F bars are and work well with sport type mirrors. Some don't like them though; you bend forward a bit more to reach them, they are like a racer's bar.
I just went out and measured my old K&N 'Freddie Spencer Superbike' bar, the center is just at 5" (needs like 4.5" to clear clamps) with a 1.675" or so rise then 8" ends, the ends tuck up so that slightly rotating the bar makes the ends dead level or a bit more they swing up if you like that. Overall width 28". Perfect for a hotrod. The OEM F bike bar is higher in lift and a few inches wider.
I've even used the clubman type bars that imitate clipons before, you just have to adjust parts so no tank contact occurs, if not willing to do that then one could say most of them do not fit. With mine my nose was right over the gauges and nothing still hit and had plenty of hand room. It's all in how you swing the rotation.
