Russ: $5,000! $2,500! Take off your Alfa goggles for moment. That's a lot of money for a non moving project car. I would be darn sure that it is complete as it is the little parts that can kill you. You are in no hurry and no one else has guts to take it on. Offer them $500. They'll come back when they realize they would have to pay someone to haul it out otherwise.
Sorry but it's tough love. Go finish your '73 - you have a lot more adventures ahead of you!
