It's a great system, I was considering, next time,  a fence to index 
the front while drilling
  to align the fronts but this sounds like an easy solution.

On a few sets where the odd key could not be made square for 
levelling, I relocated
the balance rail hole over. Sometimes the hole wasn't right from the 
start and they
bent the pin. It's a good opportunity to correct factory errors.

It is a bit pricey but it sure does the trick.
