ok...now finish? What is distance center wheel to center wheel in mm on the same scale? Actually, you can't take the bolt patter measurement that way, you have to go directly across to the center line, ummm...so, if you drew a perfect circle thru the exact center of each bolt hole, then you go exactly in half of circle to get the diameter.
make the scale as large as possible to get the best accuracy. Using the same scale you measured the diameter (I assume you used MM's), then measure the distance front to rear, center of wheel.
We are talking only 2 or 3 inches on a full scale, so I've found that it really is too rudimentary to attempt this - but i'm guessing 109.3 when they reveal.
Something like this, only use the same scale.
