I got my truck running, steering, and stopping safely for less than $3000. Then I spent another $12,000+ making it look pretty and adding more power. Not sure the pretty part of it was worthwhile since it is too nice to use as a truck. Live and learn.
There are great deals every day on Craigslist for original 235's, etc... If you have the time and skills, it shouldn't cost a ton of money to get on the road. If your truck has "real" patina, enjoy using it for a while before dropping a bunch of money on bodywork and paint.
