    You can get inserts from McMaster Carr. http://www.mcmaster.com/#standard-rivet-nuts/=i8com8 I used the knurled ones and am now replacing them with the slotted type. They expand behind the Hull and won't pull out. Install with silicone to seal the hull. Will also need a rivet nut installation tool, but can get one for around $15-20 at Harbor Freight.....
