How nose heavy is it? If you mark the recommended CG on the wing, how far ahead of that does it actually balance? I imagine that it can't be much since you did get rid of the nose wheel but it is worth checking just to be safe. Regardless, you are likely going to have a trim change so be ready for that
I agree with Chuck. You probably won't need much weight to balance if any. You moved your mains ahead but also removed the nosewheel and added a tailwheel assembly at the rear of the fuse so I doubt it will take much BUT check the CG anyway to be sure. I did a taildragger conversion to me NexSTAR a couple of years ago and I had to remove a couple lead weights on the tail after going from trike to taildragger. Here are a few pics of my setup some with the dihedryl removed from the wing also.
