Well thanks to the ported box, I found the carpet soaked underneath... So I ripped the entire sound system out along with the carpet. Not sure when I'll get new carpet put in but it'll be black! Also probably gonna rip that stupid damn box out and weld some new metal back in place to seal the cab up.
Here's how the interior sits now, I'll get the passenger seat put back in soon.
Also picked up some 15" wheels for cheap. Gonna get some tires later on and use these solely for the track.
