Small update here. I called a friend over to help me drop the other tank and look at some other stuff and here's what i found.
Here we can see that instead of just unclipping the driver side sending unit someone found it easier to take more time to cut them... right above the plug..
I sure found out the driver side was worse
If rust in the tank equals horsepower i might have something here
And the rear end... only took about 30+ minutes to get off it was like super glued on and since the breather hole wasn't plugged our friendly rain decided to drop in and party
Rust pitting the....4.10s
Last but not least we notice the steering box holes are wallowed out mainly just the bottom left one
Also found one bad rust spot in a weird spot under the cab on the drivers side on top of the frame and some more wiring issues but nothing i haven't anticipated as that's part of the cheap truck/mud truck fun
