During a nice weekend back in February/March I decided to pull the truck out of the garage and see how truly clean this truck was. My main concerns were with the rockers and cab corners. As you can tell from the pictures below, it truly was cleaner than we could have asked.
We pulled the seat, and the carpet, and started cleaning up the floor of the truck. The paint was in excellent condition, it just had 40 years of grime to clean up. The cardboard gas tank cover was still in great shape so that was wiped down and thrown back in. The rockers (inner/outer), cab corners, and every other inch of the cab is nothing but original sheetmetal.
As you can tell the PO installed an aftermarket radio in the dash, and a set of speakers, with amp, under the seat. For right now this will suffice, but this will change. I need to pull the seat and carpet again, but I'm waiting until I finish up with a few other projects before I begin work on the interior.
