You have to be quick and constantly refreshing the page. Deals only get posted for a few hours until they sell in Missouri. I'm just an hour or two by truck and flatbed over in Southern Illinois South East of Cape.
There are still old timers with acres of Mopars around, they just don't use the internet.
There's a few over by rosiclaire IL that have sat in the same spot for years. Particularly there's a 71-74 b body I've had my eyes on for 20 years that hasn't moved.
