Been planning a mk1 1.8t conversion ( for about 15 years now) Thought i might use a tdi box, and when one was advertised locally i thought buy it and worry about it later. Well its now later and i can see it dosnt have a speedo drive hole so no good to me . See several for sale on ebay so not much chance of selling it on. So i will take it apart to see how it works, its a GQQ box and i was wondering if any parts are worth keeping, cups, gear change etc for which ever 02j box i end up with, thank you..
