My DK BMX Bike that has 3/8" dropouts?

so i have a DK mp3 pro bike and for some reason it has 3/8" dropouts. I would like to get a 9 tooth driver on the back but since it is 2011 no body sells rear hubs that are 3/8" axle and has 9 teeth. is there any website that i can find a rear hub like this or is there any thing i can do i don't want to buy a new bike because i have spent so much time on it and i looked at 14mm slotted axles, but they are all sealed and they wont go on a bmx hub.
