Welcome to the wonderful, wacky world of the Chevy four cylinder era!
I downloaded your photo of parts and circled the ones I can identify (see my attached pic):
1. Red box is around a rocker arm shaft clamp
2. Green box is around a front spring bumper housing
3. Blue box is around a brake and clutch pedal stop plate. It mounds in between the pedals on the shaft that sticks out of the left side of the transmission.
4. The orange arrows point to clutch adjustment bolts
