[Dave at Pelican Parts]

You can remove the seat a number of ways. I prefer to slide the seat all the way forward using the adjuster (the loop handle--unless the loop has broken off). Then reach under the other seat rail and push up on the retaining tab in there. You might want to wear gloves, as it tends to be pretty greasy. Then slide the seat the rest of the way off forward. You can then unbolt the seat brackets and such from the floor pan.

I don't know how the POR-15 kit works, but if you have rust-through then you need to replace the metal. Pelican sells replacement sheet metal. I believe we have both better prices and better service than AA, plus when you buy from us it helps support this BBS.

The rust you show does look structural, but I think you can get away with driving the car to the shop.
