maybe someone can confirm that.
the kyb website is quite easy to use,
youll have to look it up again though, as its a flash thing i cant like you to it properly.
but for the rear i have kyb 343113 (excel G), its a holden commondore wagon or something. good shocks, not the greatest, but they are only $70 each from repco/bursons. they are still holding up after a few years of normal driving.
