Coupler pin steering box help please.

is the pin that holds the coupler to the steering box and column a solid pin or is it hollow? What’s in mine is split and hollow.... or am I missing the pin entirely and is the split hollow thing I’m looking at a sleeve of some sort? I wish I had a pic but am not near the car currently...... trying to remove the gear box and know this pin has to come out but what it’s there looks pretty fragile to me.
