Thats where the 161 came from.
I honestly couldnt tell you. I have no experience with any driveshafts other than the 6spd and the w58 one. They are all similar design just different lengths. Measure it, and check the TSRM to see if it lists the sections lengths per application.
You need a TT 6spd front half ds, you have the TT auto portion.
And just in case for you are wondering why rear half bolts up that depends on what diff you are running.
late model JDM TT 6spd, TT auto diffs, GS400 and NA (Supra, SC) diffs with TT flange all need the (USDM) auto rear portion.
The USDM TT 6spd diff and early jdm tt 6spds need the (USDM) tt 6spd rear portion.
