That may be possible but in the almost 30 years I've been messing with A-Bodies, I've never seen a 69 that came with a chrome knob or chrome top plate unless someone had changed it at some time, which wasn't uncommon, I know a few people back in the early 80's that switched theirs out because they thought the chrome looked better. You could get a complete console for $15 at the local yard back then.
I do know the knob matched the top plate, so if you have a wood grain top plate, you should have the wood grain knob and vise versa.
