As long as you are certain that the engine is original to the car, all model year 1997 to 1999 Boxsters have a dual row bearing. 
If you go further and remove the transmission, you can identify a dual row bearing by a narrow IMS flange.
Model years 2000 and 2001 are a tossup as to which IMS bearing is in there.  You can only be certain there by at least removing the transmission.  If you find a wider, more offset IMS flange, then there is a single row bearing installed.
