I believe the upside down U shaped piece is where the top of the bracket bolts to. You can see the master cylinder mounting hole in the background.
This is the 92-94 pedal and bracket.

For whatever reason, the firewall mounting studs are at an angle i.e. not horizontal. As part of my rebuild, I'll be tearing apart the dash board, so I'll grab some pics if I can figure out how to mount the 92 bracket to a 96+ body. (or if someone wants to trade pedals, that's fine too).
