I have a 70 cuda with a bobs pro fab front end with motor plates. I have the barton rocker system, along with larger alum covers. I had to notch the passenger side cover a bit for shock adjustment at top of shock tower, i also dont have a heater in the car anymore, for clearence at the back. On the drivers side i have manual brakes and had to offset brake master. Even with these mods, its tight.
