Here is a Dress / Driver / Fun / Fan ring with for the MOPAR fans. It has the symbolic "M" logo that is placed on top of the piston cylinder.
This is a Size 13 = 22.2mm ID ring - if you want a particular size just let me know.
I have just put up an illustration idea of what you could do - you could paint some blue into the centre of the ring to capture that true MOPAR feel. Select your material, colour and place your order.
