If you find any Ebi drill sheet from that time it gives all of the same layouts. The layouts from then and now are the same. Pick your current favorite Ebi asymmetric ball drill sheet and you have all the same info.
I'm almost positive this is right. I don't have the specs to the layout I have on this ball (it's still in my bag), but due to the shape of the core, any common layout for an asymmetric ball should work. This site has the specs on it, so that should help. A search through some web archive site may also turn up the drill sheet as well. May want to try that, as I'm more than positive that Ebonite took it off their old site.
