Hi again guys,
I had my rocker panels done on my 69 C20 and as I started working on the sound deadening the interior I saw daylight in the pockets of the inner cab corners of both. It's where the rocker panel ends and the cab body starts. See the pictures in my link to my Google photos.

Is this normal?
