Shift Tower Removal Question (Muncie SM465)

[fixerman]

Hi
I am a newbie that has been working hard to restore a 1968 C10 Stepside. I was going to remove the engine and tranny at the same time and ran into a problem. I removed the bolts from the shift tower and tried to take the whole thing out as an assembly. It would only move about a half an inch upward. I then suspected that the shifter may need to be removed first so I tried to drive the roll pin out but then figured out that there are two of them installed from opposite sides. Does anyone know how to remove the shift tower? I'm stuck!

Thanks,

Tyler
