Sliverado A/C condenser # change

Just received an order answerback from GM for part# 84243590 condenser.
It shows it being replaced by 84537373 and backordered (imagine that). GlobalConnect says this too but shows 84537373 changing to 84496856. also "no stock available".
Then I get another answerback for the same order saying 84243590 is replaced by 84429642 with stock available. GlobalConnect knows nothing about this change.
WTF, GM?
