Brake Rotor Confusion

I am running an older CRG with a 40mm axle and the original CRG brake rotor. I would like/need to replace the rotor however the diameter is 205mm. I am only seeing replacement rotors that are either 200 or 210, obviously not the same and the larger would most likely rub on the caliper and the smaller would work but not make full contact with the pads. Does anyone have ideas or input on this?

Did you try Comet Kart sales?

Dan, I just looked online, I see you have a 208.5, Comet and Fastech offer the 200 and 210, AKR lists a very expensive oem ven99 rotor but no measurements are listed.
