Challenger Brake clutch pedal install question

Installing the brake - clutch pedals on a 73 challenger and have a question on attaching to the firewall. Are there any additional bolts used other than the 4 from the power booster? When I took it off (many any years ago) I put 4 bolts and nuts on the assembly where it attaches to the firewall. Service and parts manual appear to only use the booster bolts.

Thanks

The support bracket located to the left also.

Correct - there should also be the little support bracket for 4 speed cars.
