When looking for some early Camaro parts, one has to sometimes think outside the box. Novas are more likely to have column shifts (I believe 68s still had dash ign. key), so do not rule the Nova sites out if looking for a column. Before comments are made about column interchangeability, I am just guessing at this point that they are the same, if not close. I am not for certain if later column mounted ignition key shifter parts (internal parts in column)will interchange either, but I would be willing to bet that the detent parts pictured are the same. If you just want that detent piece pictured, I would venture to say that many if not all GM products of the same era (Powerglide) would share the same detent. If that is the case and that information can be ascertained through research, I have a 69 Buick PG column I could help you with.
