Douglas actually makes mud plugs. I have a few of the "Champion in a Box" sets with beadlocks all around for my 450R's and it includes mud plugs for all four wheels. I would think those front mud plugs would work with your front wheels, unless your front beadlock rings are way different then the new wheels. Measure the inside diameter of your front beadlock rings and I will compare to mine. If they are close you should be able to get the mudplugs from Douglas.I still need to figure something out for the fronts.
