I got my front Konis sometime ago..
Final cost was ~50 euros including shipping from Germany. Start price at Ebay was 9.90€ but someone from Germany tried to outbid me first..
Well.. not so high price for adjustable Konis. I paid more for my rear Konis. 
And then the pics of course http://koti.mbnet.fi/mtn/images/autot/GLT/2006/koni/
Now I just have to get those installed.. 
How is they adjustable and where is the "screw" for adjustments?
Is this damper made only for Volvo 300 in this condition?
And do you know if the workinglength is the same as original or shorter?
It's made for 300-series so it will fit.

Those are not available from Koni anymore though.. Well if you order something like 25 kits then you can get new custom ones but..

They use those custom ordered ones in V360CUP, Wielhoven (
http://www.wielhoven.com/start.htm ) can supply new ones but you have to order many sets..
Those what I bought are NOS (new on stock) parts. Koni part number is 86-2182.
Adjustment is made by pushing the piston all way to the bottom and then you turn piston left untill you feel that adjusting nut has engaged. Then you can turn it left or right and adjust it as you want. Adjustment affects only to rebound.
At last summer I installed my rear Konis which I bought.

Those have worked perfectly. Rear is much stiffer than with my old Sachs gas shocks.
I don't know the working length (haven't measured yet) but I think those are guaranteed to work right at least with 40mm lowering, might have been even more.. I don't remember correctly, but they would work with lowering too. I might order some Spax front springs for front to put in with those and some polyurethane bushings for anti roll bar. But all depends if I got enough money as I'm on kinda tight budget right now..

Everything is expensive for a student..
