2 1/16 gauge rings?

[Charlie01]

Kind of an odd question but does anyone know if it is possible to replace the black plastic ring that goes around the front of my boost gauge? I left my dog unattended for just a moment and he chewed up the ring on the boost gauge. I have forgiven him but I cannot find a replacement. I have found what autometer calls angled rings will these replace the stock ring or just go over it?
