hi,i bought a quickshift for my 2wd coss from the states,it cost pennies compared to what you would buy 1 for here.i fitted it and now it makes a grinding noise when driving.i have adjusted it and it seems to do it worst in fifth.i didnt use the nuts and threaded bar they supplied as i was lying under the car and the old bolts were easier to reach.im going to put the supplied bolts in this week and see if it makes any difference.it definately didnt make this much noise before!has anybody else had this bother and what did you do to cure it?cheers,lee
