Since it's still drying and airing out I decided to do some more work. Most important was making sure that hardware went back where it should, so I put the major interior pieces back in (seats, spare tire, etc,. but no trim).
A little while ago I bought a charcoal leather rear seat out of an older Limited from fellow

member 90PioSport99 (great deal at $40), and I got that installed without much hassle (only had to drill out a frozen nut and replace a latch). They are almost exactly the same color as the front S-10 seats and look just natural. They have carpet on the back and I want to get that replaced with heavy vinyl, then weld some nuts to the frame, and bolt a piece of Herculined sheet metal to the back of it so that it is the same as the deck, but that will all have to wait a bit.
I was at the local truck junkyard recently looking for third brake lights that might work on the XJ, and found some massive steel tie-downs in a Chevy Tahoe (I think), which I also installed today. These are nothing at all like the stock tie-downs and almost ridiculous in their heft. Right now they are screwed into the floorpan but I will add some nuts on the bottom soon.

I had planned on replacing the old gas tank when I did the floorpan work, but since I had somebody else do that work I didn't do it until today. Here is the old tank, with major rust.
Here is the new tank, after I masked it off and hit it with 3M underbody spray
I also bought new straps because the old ones had rusted through in a couple of spots, and coated those with 3M underbody spray as well
I also bought a new pump and sender unit, and installed that today as well. The original was still working fine, but I figured it was close to death after 335k miles, and it would be easy to replace while the tank was out. It's an Airtex unit, so I am keeping the original parts around in case this one craps out.
Lastly, I also replaced the fuel filter with a new Wix unit, and also ordered a replacement filter bracket from Team Cherokee since the old one was held up with a zip-tie.
After all that, of course, the starter decided to take a shit and now the Jeep is sitting dead in my dad's driveway until I get another payday. But I feel good about the work I got done.
