Lock Cylinder

First, this is a great forum.

Now, to my question.  I have a 1974 Silverado, 4x4, 4-speed, NO tilt column.  The lock cylinder in SHOT, and I want to replace it, I have done one in the pass (w/ a little help), but I am going to do this one myself.  Therefore I was wondering if anyone has a schematic on the disassembly and reassembly of the column to replace the lock cylinder.

Thanks in advance,
