Got most of the interior finished up tonight, but I ran out of carpet. I need about a 20x40" section to finish behind the passenger seat. Here is what I started with, an awkward shaped piece of fiberglass:
I cut a couple thin pieces of foam to make it mostly flat
Then cut out the 2" thick piece of high density foam that really seems to absorb sound well:
Behind the seat belt you can see foam facing the other direction, there were huge empty pockets back there with some holes straight to the engine bay, I bet a lot of noise was coming from there so I filled them with foam too:
Here is the driver side carpet installed, sorry it was dark out and couldn't get a really good pic:
