I don't know if any sites have been updated since the last major bod change. There were many many threads on the UO craftsman forum that players submitted their bod reward data to. That is your best best- read through the data. Maybe someone put it all together into a single, easy-to-read post.
Here is the best I can do for you. Larges that gave barbed kits, still give barbed kits. Larges that gave horned now have a chance of giving you horned as well as barbed or a +20 (I think, If I remember correctly.) I don't remember what happened with Spined kits or CBDs.
