You are right to accept what Tony has to write. You should have a washer under the nut.
The bolt grip, the smooth part, needs to go through all of the items you are clamping together. When you torque it, you should have between 1-1/2 to 3 threads showing beyond the end of the nut with all of the washers installed. If you have less, you need a longer bolt - more a shorter bolt.
Getting the correct length bolt without extra washers is rare. You may have up to three washers in the system before you need to rethink the bolt length. Start with one under the nut, the second under the head if needed and finally two under the nut. This spreads out the stress evenly and looks good when finished.
Do a quick study of the front and rear stack ups and you will probably find the top is a little thicker and doesn't need the second washer.
(Man, I'm from Indiana and it's been tough typing "waaasher" instead Warrrsher"!)
Good Luck!
