Building a 6-door Superduty: Installing carpet and seats!

Today I installed 2 crew-cab carpets into the six door F550 (F250/350/550? I don't know! This thing is made out of 5 other trucks!) The carpet isn't perfect, but I'll get the whole thing professionally detailed when I'm done. It felt like a real milestone, since before today, this thing was an empty soup can, but now it's a 9-seater pickup truck!
