Hi Eoynteenie, I've have found that KYB gas shocks are very good. I had a set on my previous 4, and they did a great job. I've fitted them to my present car, and I've no doubt they will give good service. You should be able to get them at your local motor factors, but make sure they are the gas ones. As regards to the availability of second hand spares, on a recent trip to Reims to the car show and autojumble with Derek of Renospeed we both noticed a distinct lack of Quatrelle spares, sure you can get new parts, to a point, but it looks like the old stuff has been snapped up by the enthusiasts over there. A bit like classic MinI parts over here.
