I designed some new brackets today to lift the bumper 4" and in 2". That should fill in the space quite nicely and immensely increase my approach angle. I just don't know how thick to make the brackets. I am thinking 3/8".
I would do it tomorrow, but I have been planning an event for 450 people that is being held tomorrow night!!! Once I have that monkey off my back, I can get back to work.
