Okay I removed my old seats, just had to open up the centre console, remove two plastic screw coverers, and unscrew the screws.
My SSS seats are from a series 2 U13 and have different trim and rear armrest ski port design, i'll take some pics tomorrow.
My car had one of those Rake patented dodgy Strathfield alarm and stereo installation. The installers have removed my rear seats in order to access the speakers and run cabling for the alarm attached to the boot. They have then probably lost the two screws (one on each side) that holds the rear back rest tightly in place. I need to find some screws which fit *looks at Ka-Bluey*
If you could take some pics of the screws or show me when you or I come round, i'll try and find some at Bunnings or Supercheap.
Cheers mate.
