Best bet is to get a plug off another car with a good one. Maybe this dude can help you out - see if he can cut out the floor, and plug for you. He's in Socal so there's probably no rust. http://www.r3vlimited.com/board/showthread.php?t=345365

I had similar rust in mine. I just cut out the front floors and welded in a flat panel.
Check under your rear seats too. I had 4 holes above my gas tank and I just discovered one at the bottom rear edge of my transmission tunnel under the sound deadening.
Looks like you have a great opportunity to practice using an angle grinder, welder, and perfect those single arm (beer) curls.Comment

Mine was worse.
Go buy yourself a 4 1/2 inch angle grinder, the best 140 MIG welder you can afford with gas, a few spools of .023 or .025 wire, and 20 gauge steel sheet 4'x8'. Also a bench vise, many pairs of vise grips, body hammers, and a sheet metal break if you can afford one (cheap harbor freight will do), drill with many drill bits... I am forgetting lots but you get the point.
Dismantle the car as far as you can/ are willing to. Ideally all of it. Find all of the rust. There is more than what you have found. That isn't discouragement, that is fact. There is always more and it will run deeper then what you think.

Then start cutting, forming and welding. Prep work, good cutting discs and flapper wheels will make life much easier. Cut it all out. Leave nothing that is even slightly suspect behind.

If I had to take a guess I'd say it leaked in through your firewall and sat on your floor until it started rusting. And you live in Ohio, so road salt is probably the original cause.Comment
