I installed my rear glass trim clips on my 70 Cuda.The kit came with 18 clips plus the 2 clips the glass sits on which makes 20.I have 20 holes for clips plus the 2 holes for the glass clips that kept the glass centered.That makes 22 total.The spacing looks good for the 20 clips.Does someone know if it is 18 clips or 20 clips not including the glass clips.Thanks
