• Push the first flat plate over the bolt then pull the bolt through the whole way.
• Angle the bolt down, because if you just push the rubber first it'll flick the bolt up
• After angling the bolt down, push really hard up/inwards on the rubber
• Push through the bolt by pressing on the edge of the second flat plate
  

• Make sure to keep pushing on the rubber extremely hard otherwise it will pop off!
• Put the flat washer over the bolt
• Then the spring washer
• Then do the nut up a bit

(Tip is to have it all ready and do the washers at the same time if possible)

• You can let go and it will probably bounce out but the nut will hold
• Do this for both then use the tech gun to do it up tight
