Okay, I talked with the owner. He said he just washed the truck and that was water, and I believe him. He said the leaking is coming from the drum, on the inside, and is barely noticeable. I can get him to $3500 for this truck and it is the cleanest and most original truck I have looked at, yet.
It is a 1969 C50 grain truck, 292, 4 speed w/2 speed rear. No rust! I think I'm going to buy it.
Now, to figure out how to get it from the middle of the country down to Florida.
