That baffle is important to keep splash from the crankcase from entering the road draft tube and possibly finding its way to the outside. Put a post in the "parts wanted" forum, and somebody with a junk block will probably send you the proper part. I'm pretty sure all the stovebolt engines run the same thing, 216, 235, and 261. Fabricating something that the camshaft won't hit can be a challenge.
