You should be able to use calipers to measure the offsets and some trig to know how much of a lift the end requires.
If the hole is a larger diameter (maybe 1/2"+) you can use the calipers directly as the radius of the hole might only add a few 0.001" or so with the flat on the caliper jaw not seating fully. If small, you can insert a rod of equal diameter and read directly from the rod to the edge of the wood.
