Interior looks good for what it is. Rest of car is a toss of the coin as to what works, if anything. You know it will need everything to be useable again. Thousands will need to be spent to bring it back to life, if it is even possible. We don't know what the underbody is like. Not worth...
What do you mean, Same as Road Runner. The Fury is C body. Road Runner is shorter, smaller, B body. This one might have had potential decades ago but it worthless in my eyes now.
Since you covered the vin / sequence number, we cannot see if it is a low number. Your 8 26 build date should be early in the model year unless the experts here correct me.
Nothing consistent about the pictures. One has 2 hurst decals on left quarter panel. others do not. Many have the 300-H on front fenders but not all do and even one in a car show still did have it but not others. Very strange and disconcerting.
