the holes in the chassis ,when you get the outer bush out get yourself a 8" length of steel rod cut a hacksaw slot in the end @1 and a half inches deep,get some rough emery cloth strips,put the end in the slot,wrap it round the shaft,put it in the drill,into the hole start up and polish the hole in the chassis.gently file a short taper on the end of the new bush+a little copperslip in the hole then go for it,,,,it dont half make a difference.....best of luck mate....dave
