so I decided to fabricate a mount myself from some light gauge steel that I bent to form a channel that surrounds the tow hook, and secured it to the hook with a sandwich-cookie approach and 2 screws clamping it around the hook. Then I got a nice piece of heavy plastic mounting at Walmart and attached it to the bracket with 2 screws. I used regular hardware to attach a license plate and frame and for less than $5 I have a very secure, flat black painted bracket that can be easily unscrewed and removed. I attached a pic and a 'crude' drawing to show what I did. If anyone wants to do this it works and looks great! (I think)
