I have registered my Cobra as " A COBRA".
I wanted "21 AGAIN" or AC COBRA but I am only allowed 6 letters in the province where I live.
Other options included GORDON, SNK 427 and COB 427.
COBRA, COBRA 1 to 9 were already spoken for.
I intend mounting the plates with regulation black plastic screws that will separate the A and C. An added bonus is that the province is indicated by the letters GP at the end which happens to be my initials. Thus my plate will read "A.COBRA G.P"
