Steering Column Repair: lost snap ring, tilt column, floor shift

Question
where do i get a new one for a 1978 c20 pu non tilt floor shift

Answer

non tilt Hi David:
You need to give me a little more information than '78 c20 snap ring'.  Here is a blowup of a GM non tilt column (I think that's what your "c20" refers to).  Let me know what part you need from this (if it's the same)
Then, we may stock it and be able to get you one fairly fast
Thanks
Doug
