Bob,
The truck had to sit in one spot for a long time to have a vine rust the fender out...is there rust above the windshield on the inside? How bad are the door bottoms?
Don't mean to burst your bubble, but unless this truck has special meaning to you or is free, you might want to pass. Running and stopping farm trucks can be found in the $2000-3000 range...it will take way more than that to get this truck safely on the road. How long has it been since it ran?
This truck will not run at modern hiway speeds empty and will be even slower loaded, so the stock brake system will be fine after it's been completely replaced including the steel and rubber lines.
