Steering Column 67-68-69, An exploded Veiw

Can anyone help me, I am looking for an exploded veiw for a 67 A body steering colum with column shift so I can put my steering colum back together, Also how do you get the plug off the wires to the signal switch? is there a tool to remove the wire so you can pull it through the column?
I have the one for the 1970-1971.

Thanks Mark.:cheers:
