turk. what im trying to explain is the bolt itself not the plastic washers that go on the inside. i hope its not a big deal because i didnt use any. thanks for the reply. i used 4 of those plastic washers on the flat side,and 2 on the other side. except for one weight. i had to use the ones that came out of the bender clutch kit witch were thicker so i used 3 on the flat side and 2 on the other side.
