That would be a .68 tang undivided turbonetics turbine alright. Another bit of information for you, I'm not 100% sure because looking at photos can be deceiving, but it looks like your turbine has been "clipped".

Because if you look at the picture, .68 is clearly stamped on the turbine inlet as it is in the majority if not ALL Garrett / Garrett based turbines including Turbonetics.
Turbine discharge diameter has not one thing to do with turbine A/R withen the same families (in this case T4).
