Well Just wanted to follow up. This may be obvious to a lot of folks but it might help some others. I took the disco out to my shop and used the jaws of my vise as a base to hammer on and the disco pin moved right on out easy a pie. Evidently hammering on a rubber gun smithing mat absorbed the impact of the blows and wouldn't force the pin to move. Oh and also used a nail set since I didn't have a small starter punch on hand. But it was mainly the firm support that did the trick.
Edit: Used the vise to press the pin back in and that worked like a champ.
