I've bought door lock cylinders and keys from my local parts stores--Standard Ignition and Filko both make them,also trunk locks for cars--as for the tailgate,they might list them too,(it will be just the lock cylinder,not the handle )but if they dont you'll have to try the other truck places already listed,or a place like Harmon's,or Brothers,Cheyene Truck Parts,etc. /forums/images/graemlins/crazy.gif
