Can someone measure their calipers, please?

If someone with a 600RR happens to have their bike apart and a caliper available, can you please measure something for me?

I need to know the diameter of the inside (mounting) ring. Basically, the ring that fits around the wheel when the caliper is bolted on.

I'm looking to put RR wheels on my F4i and my only hangup is the rotor size of the front wheel. If the mounting ring is the same, I'll be able to swap rotors across and make it work.

I would measure them for ya, but my bike is in one piece

I found out that the 600RR and F4i calipers mount up exactly the same. The RR calipers just have a larger rotor surface diameter though the mounting ring is the same size.
