The carpet replacement project proved a bit more complicated than I had anticipated. Once I got the seats out and pulled out the various console pieces, I pulled up the old carpet and found that the rear passenger-side footwell had started to rust.
Thank goodness for POR and fiberglass repair kits.
I was also amazed at the amout of junk under the consoles. I think the car was parked outside with the top up for quite a while at some point.
