I have found many of the pieces you are looking for are available from Superormance. If they are clones, they've done a very good job. I purchased my dimmer, heater and wiper knobs from them

My air vent knobs came from VictoriaBritish. You'll need to take your chances on the quality. Some are engraved and filled with white, others are just hot-stamped with white.
