I have a steering column from a 1979 Chevy Carpice. I need to change the turn signal stalk. How the heck do I get it out of there? It does not appear to unscrew, with some force I am able to twist it , maybe 30 degrees, but tht does not accomplish anything. There is what appears to be an access panel on the column, but I can seem to get that out either. I pulled the wheel off but that did not get me to what I needed.

Any one with experience in such things, or a Helms manual that has instructions, I would be in their debt if they could tell me how to do this.

thanks

Pat
