Thanks for raising this point. I believe you're correct, but confirming this requires catching details that aren't immediately obvious.

The parts lookup shows that there are two supersessions for the current part number, so it's easy to guess that this means the BRZ used two different earlier revisions before landing at the current part. However, this is not the case.

The key is to not just look up the current part number, but also explicitly check the supersessions. It turns out the current part number supersedes parts that go all the way back to 1997. The two superseded part numbers cover cars up to 1998 and 2009 respectively and were already out of the picture before our twins.

Same with the pivot ball; the one superseded part number went up to 2009, same as the second clutch fork.

What I'm intrigued with at this point, and don't have an answer for, is where the WRX fork fits into all of this.

While this doesn't directly cross-reference to the BRZ, some of the other vehicles listed in the applications also show up in the application list for our fork. The non-WRX, non-Turbo cars listed (Impreza, Outback 2.5L 5MT for 08-09) for the WRX's fork, appear to also show up in the application list for the BRZ fork.

Searching by application for say an 08 Impreza, both the WRX and BRZ clutch forks show up.

This suggests that the WRX clutch fork is actually interchangeable with the BRZ part.
