250-500cc CR/WR 250/300 crank measurement

I'm hoping there is someone with a 2000-2014 CR/WR 250/300 crankshaft laying around or an engine out of the bike and has the tools and ability to give me an accurate measurement of the taper on the flywheel side of the crank. According to the parts catalog, the cranks have the same part number for those models and years above. I need the measurement at the widest part of the taper, the narrowest part of the taper and the distance between the two in mm preferably. I'm not too proficient with calipers and it's hard for me to get in there with everything in the way. I've attached a drawing of what I got measuring mine, but I need to be really precise for HPI to try to find a rotor that will fit. Disregard the bottom drawing.
