alcgar: These guys are tight on how to determine the cut. All John Deere operator's manuals of that day had a section on "Plow Hitching", and cover from 2 bottms up to probably five. I know the plow does not pull, or draft right up the middle, but needs to be offset. To determine this compensated "Centerline of Draft" , find the point 1/4 bottom to the left of plow centerline. On a 2-14 plow that would be 14+ (1/4*14) = 17.5". So your drawbar hole should be 17.5" from the inside of your right, or furrow tire. If you can't adjust your wheels that much, you can set the drawbar to the left a few inches to create the 17.5". You also don't want to pull down or up on the hitch as you plow. This same draft point is at 3" when you are plowing 6" deep, so the line from that draft point to the tractor hitch should be straight line. You adjust that with the clevis rack on the front of the plow. Get yourself a JD ops manual, or borrow one from a "B" on up. You'll be surprised at the amount of information.
Hope this helps !
