transmission linkage

I have a 90 Integra 5sp. Just finished replacing the tranny and I think I put the linkage arm back on upside down (the throw on the shift tower doesnt have the correct distances). Any one know a good way to get the pin out of the linkage that attaches to the tranny unit? I did it when the tranny was out of the car before. I have been trying to use a punch and tap it back out but it isnt cooperating too well.

Thanks Bob
