Some Nissan left mounts are labeled LH and some are just L. You can see the heatshield that goes on the left mount also has 2 siamesed holes in it for the mount bolt and 2 locator pin holes. That's so it can fit either an LH mount or an L mount.
IIRC, the KA uses L which has it's bolt about 3/8" further rearward than the LH mount.

The left mount I have is labeled "LN." Regardless, here's the scoop from Nissan Motorsports per phone call:
1. The number on the RIGHT mount is a JDM part#
2. The NISMO part# does not show on the mount b/c they use the same machine to cast both OEM and NISMO mounts but with different material.
3. By using the same machine/cast, the OEM part# is embossed on both parts.
