FG 345 with a broken neck heel

High action is common with 45 year old guitars, from 45 years of string tension pulling the neck up.  A broken heel isn't quite as common, but it happens.  The only right was to fix it is to remove the neck, pin the break from the inside, and do a neck reset to fix the angle.  I've done a few.  But the repair is very expensive, far more than the guitar is worth.
