Volvo OEM rotor with unknown part#

Hi all,
Today I put new tires and looked at my brake pads as well as the rotors. In the near future I will need to redo my brakes so the question that even the parts guy will ask is, "do you have 280mm rotors or 302mm?" Well to my surprise I'm running OEM rotors (thanks PO) and this is what I got from the passenger side: VOLVO 31257613 1 MIN TH23mm 120518.
I'm running this part number everywhere and I can't find any info on it. Maybe this is an old part # but is there anyway I can figure out what this is? I didn't have my measuring tape with me at the moment which means next time the wheel is off I will need to measure the rotor

Anyone with VIDA can shed some light with this number? My VIDA laptop doesn't want to boot anymore so I can't access anything.
Thanks, Rigs

Can't find that part number on Vida. Volvo do many strange things with part numbers so it could be an old part number (check with the dealer, they should be able to look up and see if the number is a good number and been superseded) or a sub-part number of a kit.

Only real way to find out is to measure the diameter if you are not sure they are original to the car as it left the factory.

Thanks Scot,
I might stop by at the dealer sometimes but since I have some front end work to do I'll measure the rotors myself. Here's the picture I got for the passenger side:

This is a 280 rotor. The 302 rotor has vent holes in the groove between the brake pads/brake surface and the surface where the parts number is on.

Thanks for the tip Clemens! I'll keep that in mind when I'm at a junkyard looking for stuff
