How do I remove the input jack on a Silhouette Special?

Hi all, I’m working on a Silhouette Special and need to remove the input jack. I’ve never done this on one of these before, so I’m hoping someone can point me in the right direction.

What’s the proper way to access and remove the jack on a Silhouette Special? I removed the jack plate first and used a 13mm socket to unscrew the ring but I am having trouble trying to push the jack out from the inside.

Thanks in advance.
