Adam found one on Craigslist. Dana 80 with disk brakes and all 6 wheels and tires. It was right across the state line in Alabama. Long drive for us but he only gave $400 for all of it.
The 97 is 8x6.5 lug pattern and the new Dana 80 is the metric pattern but we're going to put a Super Duty front end in it to make 4wd anyway so that's why it didn't matter to us. Plus, we got the front wheels and tires to boot.
