If you are referring to the bunk-end screw clamps, you can find them on ebay for $10 each. I just did both my bunk-ends last month. When I got them, the screw pattern was opposite of the original holes on my camper. So in order to make then use the existing holes (I didn't want to drill new holes), I simply used pliers to bend the 90-degree "stopper" up so that the latch can swivel a full 360-degrees. Then it was as simple as unscrewing the old ones, cleaning the area, apply some sealant (e.g. Dicor), and screw the new ones in.
