C2500HD 2019 Duramax Owners...Recall related

Question for all the Duramax owners and the recall associated with the block heater cord. Called the dealership to check on the status of the part for the block heater recall and they told me all the available parts are going up north since we don't need them in the south. I partially agree with them...but since I could be going extended TDY to Cleveland and I want to drive my truck rather than flying since it's and extended timeframe...I wonder what luck I'd have in getting that block heater cord replaced before I go...or would they tell me to find a dealership in Cleveland?

Anyone have any luck getting that replaced on their truck yet? Thanks.
