I have too seen the picture of the Strickler car with no wing windows. So was that a racer or factory modification? This also means the 2% cars could have had aluminium doors along with a A864 single headlight grill. I think it is probable as the A864 cars were nearing production and the parts were probably available. The 2% cars were the last evolution of the Max Wedge cars most likely.
My next question is, were the the A864 Hemi cars faster right out of the box than the Max Wedge cars? I would not have thought so with the Max Wedge cars having over two years of development on the track. I would figure the teams would have used what ever they could off of the new programs on the old platform till the new package would out perform the tried and true.
