Figured it out a few months ago. Where I thought the floor and extension were all part of one long piece, turns out all I had to do was pull the seats out again, and the extension came loose right away. It was being held in by the seat's bolts, solely! Now I just need to find a decorative trim for the edge of the carpet line. And the side door step is kind of awkward as its for a cargo van, not a pass van. Maybe I can source a couple at a pick n pull

Late to this party, but for my 2012 FTC I got a 6' foldable ramp. The "EZ Access" one, that you can find on Amazon, and even with free Prime shipping. Folds up & stows away great.

Any updates or photos of your seat installation? Bought a cargo model 2012 TC XLT, dealer bolted in some seats for me so I can use the van both for work & play. But the floor extension leaves NO foot space for anyone riding in the back. There's carpeted flooring beneath the extension that I can see, I'll probably need to investigate myself how easily the extension can be removed. And whether that'll cause issues in preserving mounting points for my backseat :/
