Source for struts for the cabrio trunk?

My 1993 Cabrio trunk barely stays up, and really needs new stuts.  I ordered a set from eEuroParts.com.  They specified they were for the Cabrio, but what arrived was 2X too long and obviously for the hatch of a coupe.  

Does anyone know a good source for these?  I think of them as a commodity item where you could just match size like windshield wipers, but I went to 3 autocrats stores and they said no, you have to order by car, and we don't have them.
