The resistors in the Werkstatt are 0805 size. Sometimes you can fit a 1206 size chip in the same spot.
You could buy some of each.
However, since you seem to be new at this, I'm not sure that trying to do the fix yourself is a good idea. Try contacting Moog and see if they can cover this under warranty.
