I don't have plans at home so I can't say for certain but I think the answer is yes.
The plans have you initially leave the holes in the window under sized for the hole to act as a guide in helping to assure you tap the hole in the roll bar straight.
Once the holes have been tapped, you enlarge the screw holes in the window for a slip fit of the screw (the screw is intended to thread into only the roll bar).
