Need measurements for JP holes in the backplate

Like the topic says.... Exactly where do the square/rectangular holes go for the JP straps??? I guess a measurement from the bottom of the plate would be best as that is where there is a straight surface as opposed to the rounded shoulder part..

thanks for the help all

Although someone could certainly figure out the exact size and locations of those holes,
I think it depends more on your harness system as well as the size/weight of your jet pack.

If you base the holes on pre-determined measurements, you might not end up with a
comfy fit. Your harness straps could also end up putting excess strain on your backplate.
