I just spoke with Mr. Montgomery about the '71 383 'Cuda. Here's the lowdown.
Real 383 car, but a non-number matching 383 is in place
Automatic - the correct one in the car
No trunk lid
Floor pan rust
GB5 - True Blue Metallic
Missing fenders
Was a parts car
He said that he has plenty of cars with parts to complete this one. So, if you're interested (I am), it's a restoration in waiting.
