1971 Demon 17" Help

For the fastback Barracudas to achieve what the Valiant cars can (wheel/tire) you would have to mini-tub the rear and lose the cool folding seat. The wheel opening don’t lend themselves to being pushed and rolled as well as the Valiant’s. They seem smaller in the already tight areas of the Valiant’s.

Now, I say Valiant in reference to Demons and Dart Sports because they are basically Valiant just like the Duster. However, the Dusters, Demons, and Sports have those big back hips! I like big butts and I can’t lie.

In the back of the car that's actually not true. Barracuda's have the same inner and outer wheel tubs as Dusters/Demons/Dart Sports, or in other words 1" more than the hardtop Darts/Scamps/non-sport body cars. Like for like as far as stock/mods go Barracudas will take the same size rear tires as a Duster/Demon/Dart Sports

The problem is only the front fender, the front lower corner is more restrictive than any other A-body. But that mostly affects tire height up front, for width they're as good or even better than the other A's. And a small modification to the lower front corner is easy enough and solve the height issue.
