I stand corrected
Heidt doesn't build a Mustang II kit for model A's . The super ride Is a Completely different design with rear steer, different spindles. arms and works. The old Jag xke conversions also would fit under the fenders, but most I saw had solid rotors, not as big of braking system as the Superride. I had 3 Mustang II pull-off when I bought the A and that was when I checked.
