The drivers side lift arm on my 85/2 944's sunroof has snapped. It has the old style cable push kind not the gear driven kind. My question is, does anyone know if I can replace just the one arm (it seems to be connected to the cable)? Or do i have to buy the whole system? If I have to do the whole system, how hard is it to remove the headliner that covers it. Any suggestions?

Thanks,
Jon
