Pelican Parts Forums - 944 turbo struts wrong size help!!

I ordered new struts for my 91 turbo as one froze whilst it was on the lift for a while.

The first ones came in wrong as they had no shield attachment and various other bits were wrong.

Now the "correct" ones have arrived took them to the garage to get the springs swapped over and they are 20mm to short - argghhh.

they are off an non mo30 suspension and are sachs part number 312 309 and 312 310 (left and right) checked them of the sachs catalogue and it says these are correct but they are too short. It weird because they look exactly the same but the spring cup is lower!

Does anyone know the correct parts number, am I missing something

The garage said just to fit them and enjoy the lower ride height but not up for that, help!
