Dash removal

In my 67 notch, The original hardware is about the same height above and below. I turned the U nuts on upside down, original bolts in from bottom up. The bolts weren't long enough to cause a problem. It seemed to be a good plan at that time (6 or 7 yrs ago). It didn't take long for me to realize that I would never remove this entire dash again. Other members here have stated the same experience/revelation. We agreed, what's done is done.
