Sure Wes,
The yoke (hold down clamp) with the wider openings is the front one. Reason for the wider openings is for the saddle to be pushed _rearward_ that much more (the rails start converging/narrowing toward the front and the wider opening front yoke allows for the narrower spacing towards the front).
