Received the trim panels for the deck and climate control.
The deck is easy - I put to screws through the metal mounting flanges into the plastic behind it, so it's not going anywhere. The trim then snaps perfectly in place.
The climate control was more difficult. With the plastic trimmed, there's no real easy way to secure it.
Then I came across this stuff mentioned in another thread (babybmw.net):
You heat it up, and it becomes a pliable silly putty like substance. When it cools, it's hard as regular plastic.
Pour some in a bowl of hot water:
It eventually clumps together and you can mold it:
I spread some on both sides of the climate control cage, where the factory tabs on the climate control unit would make contact:
I then pressed the climate control in - and the thermomorph self conforms to the factory mounting tabs:
Success! Looks perfect!
