What those instructions neglect to say is that you should alternate reaming small amounts out of each hole if there is any chance of serious misalignment, that is:
1. evaluate the two bushings and use the best one(hole a) as the first pilot hole,
2. ream the worst hole (hole b) only until the it "cleans up"
3. use the newly cleaned up hole (hole b) to pilot as you ream hole a to size,
4. finally pilot in hole a as you bring hole b to size,
this way all misalignment is removed, just reaming one and then the other will be satisfactory 99% of the time but the first hole will usually be cocked with reference to the next hole.
