Default Floor repair project

I posted a while back asking for some pictures of the floor and then have been silent for a while, between work and it being almost 100F every friggin day until well after 9pm the truck hasn't seen much love in the last month or so. Well yesterday the high was only 83 so I got out and got after the floor situation.

So this is what I was dealing with. I went to install my e-brake and found that a lot of the floor is gone. Most of what was there under the pedals was so thin you could just poke through it with your finger.



I scraped all the insulation stuff off the floor so I could note any places where the rust was beyond a some sanding and POR-15. Most of the floor under the seat is fine, just the pedal area that's really bad. The angle grinder and Dremel have been put to a lot of use in this so far. I've just had to keep expanding the hole out until I see I'm cutting into good steel instead of rusty garbage.

BTW anybody know what this thing is? It was in a hole behind the kick panel. I had to remove it to cut the metal out around that area.



The wheel well is rusted up as well. Some of you guys might remember back in '13 I cut out a bunch of metal in the engine bay and riveted aluminum sheeting over it. Going to cut all that out and put steel back in. Also while in there I cut the end off the rocker panel and am going to plate that off so I can put a little spacer in for the wheels so it's not scrubbing the frame anymore when at full lock.

Ouch. Did you have a long-term leak to the inside (so wet carpet), or was the floorpan rusted only from outside/below/front?

No leaks while I've owned it, the truck spent a few years up north according to the Carfax so I'm guessing the road salt and junk in combination with the frequently problematic AIV box is what did it in. When I finish with the driver's side I'm going to check out the passenger side and see if its got any. Just looking at it under the truck it looks ok.

Maybe wet/salty snow boots by the prior owner(s) up North?

Posts like this make me realize how lucky I am with my $1 truck. Are you just gonna cut all that out and weld new sheet metal in? Seems fairly straight forward but still hard work.

Also, I like that 190D. My first car was an 87 300D. Miss that car every day.

Yep. I got a bunch of free 14g sheet steel a while back so I'm gonna use that for the floor. Probably use about 3 sheets of it for the cab mount area and then gusset it for a bit of extra strength. It is fairly straightforward but you're definitely right about it being a lot of work. It's hard to get tools in and around that area without pulling the whole cab off the frame as well.

Ouch! Nasty!
Object in kick panel is your seatbelt/headlight/key chime.

IMO, I would find a truck that has good floor pans at the j/y and cut them out and use them as patches. I know, I know, finding good pans is hard to come by. Just a thought.

I wish I could get some actual floor pans, yards around here don't keep anything older than 10 years for whatever reason. Just immediately gets scrapped.


@Cajun thanks! I love that car, haven't been able to drive it in a while sadly, stripped all the interior out to clean it and have been doing a full amp/speakers/etc. install while fixing some interior things and it just keeps stretching further and further... haha


I did some more cutting yesterday after work. Got the POR-15 out and sanded/painted the rusty parts of the floor that seemed to still have good metal. Still have a good bit of cutting to do but I think I'm at the point where I can at least weld in the area around the cab mount.

That's sad to hear. Have you thought about calling yards in the SW and see if they would ship the panels to you?
