parts availability for Nexus 7 gen 2 LTE

I don't know if you are the one to address this to but ...

I want to replace the back cover and the charger port board in my Nexus 7 LTE tablet. Both of these items are currently out of stock, I have left notification on the pages to be notified when they are available, but might you ( or the parts dept) have any sense as to when parts might become available?

charger port / Item Code: IF235-030-1

rear cover / Item Code: IF235-033-3

-- I must be hard on the Nexus , I have already replaced the the motherboard through you.

Thank you

Ron
