Update...the partshouse is reimbursing the $42.00 spent on cutting the new Drums.
Two new sets were factory cut out of round and they said that was unexceptionable, and it's about making it right for the customer.
I come to find, "Silent Stop" is not the manufacture but a brand-name created by Federated Auto Parts.
Also...as I mentioned prior I did NOT install the second set, I took them to a shop I know and a the fella I know checked both Drums right in front of me...both were bad. I believe .020 +- was cut from both to make right.
