NUTSERTS, another thing I have never done, easy!! just alot of them, close to 100 to hold on the 6 panels of body armour/fenders. I used 10-24 pitch, steel Nutserts. Bought stainless steel pan head square bit machine screws (McMaster car catalog comes through again) to prevent rust and to give a smooth finished look,,,also did not want to have hex heads hanging up on clothing etc.
