The tire tool worked perfectly! Thank you both for replying. Later I will compose a proper introduction for myself and the car as I would like to see if it's a "known" car. Thanks again.I use a wooden dowel from the inside. Catch the lip and tap. Have a friend there to catch the cap.
Strange that Ford carried over the 38 deluxe design for 1939 for the spider accessory hubcaps instead of using the new 39 deluxe pattern.
Here's the tool I made. A simple slide hammer pulls the hub cap from the front rather than pushing from behind. No helper needed. Hook it, tap-tap and done.
