2nd Gen Non-Engine/Transmission 3rd gen exhaust brake 2nd gen manifold, please help!

[01cmns]

Good morning/afternoon, this is my first time postin, just signed up. I have an 04 dodge cummins with 2nd generation style manifold. I am having a hard time removing clevis pin on the exhaust brake butterfly flapper. I found a thread in this 2nd gen section that talks about it but the pictures posted are not found. The reason I am trying to remove is for actuator clearance issues with ac lines. I need to move the E brake actuator 180°. Do I just keep hammering pin with punch or am I missing a step? Below is a couple pics. I posted here because I found a thread about clocking actuator and pushing pin out to spin arm in butterfly valve. Thank you all in advance.
