Going to mini-tub the 69 Firebird, anyone ever done one? I am building the car to the G-Machine/Pro Touring style. So big fat rear tires will eventually be the goal. Doing the suspension now so going to do the mini-tub now. If you have done one, what did you use? I was looking at the Competition Engineering mounts, but they look like they will lift the rear of the car about 1/2", trying to determine of that is the case.
