They will. Used them. Not as convenient as the ARB fix though. The ARB is instant, and very easy to carry. Easy to separate too, if needed, and just as quickly. AFAIK, ARB simply calls
theirs 5mm because metric is the local standard. Or so I have been told. Very close if not identical dimensionally.
