I received my part today and there are no holes drilled in it. Can you tell me why?

We do not drill holes in some of our parts because when we recast the part it shrinks an 1/8" per square foot. Also if your stove is an older stove the heat of burning the stove could have slightly changed the location of the part. If we had drilled the holes they would not line up correctly, causing problems with the installation of the part. So we have found the customer needs to mark and drill the holes in order to have them line up correctly. The holes should be marked and drilled with a standard drill bit BEFORE the cast iron part is seasoned.
