Trying to save a ‘66 Barracuda

Pre 68 Trans will have a small snout to match the early crank, then it got big in 68 so they don't cross over unless you put an early trans on a later crank with a bushing. Try and get a matching pair. The 66 was a one year fender and grill as you know. Going to a 63-65 clip is bolt on , even off a Dart (Canadian models were half val and half dart for some reason) iirc the Duster 904/8.25 was the same length as the 66 904/7.25 buy I can't guarantee that. I wanna say 49.5"? The rad support will be 4" wider on a post 66 car.
