Bleed Boss Cap - Substitutions?

Part in Question... Y2HW1000 - Bleed boss cap - Ultegra BR-8170 Brake Caliper

Not surprisingly I'm unable to find a direct Shimano replacement. Before I break out my micrometer and measure it and begin my Internet search I was wondering if anyone has a tip where to source this part or a workable substitution?

I was kind of figuring that was going to be the answer. At least I have 1 that I can take and size up against what they have in stock.
