Identify these brackets

[69L78]

Trying to identify these brackets. I know the one is a throttle bracket for a Chevelle p/n 3972291 but not sure what it is correct for.

I recognize #3972291 as an accelerator cable bkt. for a 1970-75 6cyl. Camaro,Chevelle & Impala series.

The 3 on the right look like carb fast idle/idle stop solenoid brackets with that rectangular hole.

Looks to me the two on the lower right are tranny shift quad levers ... TAZ
