1997 Corolla Seca - Toyota spec for 68960 YA 020 rear hatch struts?

[celicadog]

Hi, does anyone know what the correct Toyota specification is for the rear gas lift hatch struts for a 1997 Corolla Seca (with spoiler)?

The Toyota part number is 68960 YA 020 if that helps.

If anyone owns one of these, the pressure will actually be written on the side of the strut quite clearly. My struts have 0420N written on the side, but these are the wrong struts unfortunately, and Toyota wont tell me the correct specification - they just want me to buy their genuine parts which I would if I could afford to.

I also rang Stabilus, (the actual manufacturer of the strut), and they will not tell me the correct specification either unfortunately.

I need to know it because I am purchasing some aftermarket struts but they need to be gassed with the correct pressure.

Any help is very much appreciated,
Chris
