PW Steering Column, Need Help

Yes there is a pin. I believe it can be removed but I've never removed it. It probably will require a press or large vise.

I have a Flaming River B-Body column now and never had to get into the factory columns. This is why i know lengths as I converted to Power Steering and wanted to know if the B-body column would work in an A-body and it does if you cut the D-shaft shorter.
