Mike , what I said was that all R33 Skyline shocks are coilovers, ie. the coil goes over the shock.
What you want is a height adjustable one which is done by winding the springs up and down using a c spanner.
A lot of the cheaper new Koni's and Bilsteins use a circlip type adjustment which requires the disassembly of the spring/shock to achieve a height change.
Wilkinsons do a Aussie brand style adjustable platform coilover which may be in your price range but will check Monday.
Fialing that will check to see what Whiteline sells ( as we are an agent)
And as I said a quickish height change is good for show/go/sticker removal
Cheers
Ken
