Hi all. Quick fitment question for a project. I've seen plenty of folks asking about rounding off square lens boards to fit Deardorffs that take rounded boards but my question goes in the opposite direction. Will Deardorff lens boards (6x6) with rounded corners fit Deardorff front standards made to take square boards (military Deardorff's for example were made to take square boards). Wondering if the boards will fit for if the rounded corners will cause light leaks. Thanks.
