The broken heart will heal. Sorry to hear the car was damaged but above reads like you'll get past that too.
Looking forward to learning the actual cause of sudden lockup. I met a guy who has a 69 Charger in his carport that hasn't moved in years. Many years back when he and his brother would drive it and drag race it, it locked up on the dragstrip... full story, it happened twice. Scared his brother away from the car.
Back when I met him ( he put new roof on my house about 5 years ago ) He told me he has another dana 60 rear to put under it but he doesn't have time for it and brother wants nothing more to do with it, so it just sits there.
