peterOZ , use offset shackles, roll the fender lip, and use 275 60s with the right offset rims to fit, and some cal tracs traction bars instead of butchering the car up. The 67-69 barracuda wheel well is pretty wide to begin with.
Besides the spring relocation, you will have to cut the inner wheel houses and move them in against the framerail. This will affect the finished cargo area and rear seat in your fastback. Dont do it!!!
