This note is found at the Sludge Hole, on a wooden crate next to a pile of yellow barrels.
Make the deal to trade for parts. This sludge pit is a cap well, but if we can't keep things running our stocks are not going to last long. If the Top of the World decides we're unreliable they'll come down here and take everything, including our lives. Secure the parts, whatever you need to do.
