Ooh. Fun.
1. Maybe part of the evap cover? Edit: nope.
2. Smog pump bracket, but the perspective makes it look too long. Edit: also nope.
3. Firewall bracket for the accelerator linkage. There are two kinds, one with the extra part that points down in your pic. Anyone know what that's for?
4. Looks like a motor mount bracket that would attach to the engine, based on the round shape. Edit: strike 3, 2f motor mounts are made like those from a tank.
5, 6, 7. If they're FJ40 OEM, I'm feeling dumb. I don't recognize any of them.
3. I have seen speedometer cables routed / retained on the Torque Rod Bracket Extension arm before
