The tunnel size created some conflict with pedal orientation heads up. I have mine quasi located. But I used the booster from the donor SRT. I am at the point I am considering regrouping and going with a smaller Wildwood unit. But I have to be choosy where I spend cash and I have the OEM pedals and booster from donor car so that is cash I save and can use somewhere else. Do I like the size of the booster? Heck no but the price is right! Likely change later but for now I think I will rock the mondo booster. I need to modify the inner fender a bit to accept the donor booster. Not the end of the world but yet another pain in the butt. It never stops!
