noel its not neaded if you wanted just keep a 5mm thick piece like the piece you cut off stick that under the cup and use the long bit ontop of the topmount !!!!! your tyres will be rubbing the arches then also make sure to measure before working on the 2 holes on the front struts !!!!!!!!!!!! massive camber if just enlarging them !!!!!!!!!! so before filing mark it where you want it !!!!!!!!!!!!!!!!!!!!! the bottom bole closest to the shock and the top 1 out wards so you get an idea of how to where to !!!!!!!!
