Turbo turbine shaft replacemnt

So im looking to get my turbo rebuilt but stock t3 turbo i have has a broken turbine shaft so i was wondering if anyone happens to know the spec on the stock one so i can replace it. I tired calling nissan but they had no idea my next bet was to call garret but its hard to get a hold of someone on the phone who can help me. When i look online i get different sizes and am not sure how or what they measure for the specs. My plan is to get a new turbine shaft and rebuild kit then send the turbine shaft to the link below to get it balanced (55$ is not bad) then s;ap it together and ill have a decent turbo for a fair price. Thanks in advanced i don't like begging for answers but ive looked just about everywhere i can think of.

Better yet if anyone has one their willing to sell ill buy it and or if anyone has a trashed t3 with a good turbine ill buy that as well.
