Might be awhile on the pictures. Moving to a bigger garage with a house attached ! LOL Will post them asap.
Attached with four screws upside in the window track and nuts on top of the fiberglass. Thought about using tension buckles but I don't think it necessary.
I finished the bottom with Herculiner. It deaden the sound a bit and was very easy to apply. not as shinny as the picture looks.
