It's a craigslist deal.1985 Olds 442 80k 8.5 rear end non posi with 3.73 gears. I offered $450 he replied with can't take a loss & said $600 is what he payed. My best offer went to $500 cash & I'm waiting to hear back from him, he seems firm on 600. I plan to add posi to it as well so add another $400 to that is around the $900 range
