Carpet is cleaned up now, here's a few more pics of how bad it was:
When I replaced carpet, I didn't use the stuff from Rockauto.. I did some research and found people thought the carpet from accmats.com was the best, so that's what I went with.
It's important to spend a lot of time making it right, or it won't turn out good. You have to cut holes in the molded carpet, so it helps if you have the stock carpet to use as a reference.
I actually cut out the pans and some other areas to bulk up the replacement carpet, as it just wasn't thick enough in a few places, even with the extra mass backing. I used glue to ensure a good fit almost everywhere. Even spending all this time, I still ended up with a few areas where it just wouldn't lay completely perfect, nothing to really complain about though.
