Hello! I'm a new member here on the forum. I have a 1968 6117 Double Anniversary that has been through the ringer. In the self-made luthier craze of the 70s, someone conducted various experiments on it and now I'm trying to get it somewhat back to what it started out looking like. Unfortunately, when I was trying to put the truss rod cover back on it, it crumbled in my hands. I promptly found one online and ordered it but it's too short. The part I got was a 60898000 which is just over 2.5", but I need one that measures closer to 3". Most of the searches I've conducted online keep bringing up the same one that doesn't fit. Does anyone have any suggestions as to where I could get a proper one? If anyone knows the correct part number, that would be great info as well. Cheers!
