I don't know the correct way to properly measure for this but here's where mine are located:
The middle of the emblem (point directly below the "deluxe" script) is 6 5/32" forward of the rear seam.
The point under the "deluxe" is 5 3/4" above the crease that runs the length of the qrtr panel.
If you need better (more accurate) measurements, or don't understand the ones described above, e-mail me.
