Hole (#27) centerlines were 5/16" along the (short) edge. Presumably this material would have been used for the rear windows also. The use of overly thick material for rear windows will cause the aluminum skin to "pucker". The additional stiffness of thicker sidescreens reduces the normal ease of operation, due both to the additional force required to cause the change in shape of the panel as it moves up and down, and less clearance in the channels than was originally designed. There is also the consideration of the unnecessany and useless extra weight of using thicker material. Lexas is MUCH stronger than Vinylite or Plexiglas for a given thickness. For anyone making a flat windscreen, Forney used .083" Plexiglas for their bubble units. Regards, William R.
