Hey Greg, I checked with Dometic, and the flush ball is not replaceable for the Dometic 300 toilet # DOM64FR that you have unfortunately. The only serviceable part for the 300 regarding the flush ball is the Replacement Flush Ball Seal # DOM63FR.
Otherwise, if the flush ball is broken, you can replace the toilet with the # DOM64FR
