I ordered some parts yesterday afternoon from Summit Racing Equipment and they arrived this morning! Talk about fast. The master cylinders and the balance bar all seem pretty well made. There are a few product PDFs on their site that show drawings of this balance bar, but none of them give dimensions which is pretty surprising. So I thought it'd be a good idea to post some of the more important dimensions as measured by calipers in case someone needs them as well as a pic of it mostly taken apart to show how it works.
