I'm installing a BFG9060 in my A3000, and the instructions mention that after installation and testing, it is important to install the four "nylon standoffs around the KEL area". What is that? I don't know what these nylon standoffs look like,but whatever they are, I haven't got any. Can anybody direct me somewhere I can get some, or at least give me a proper name and description so I can hunt for them at the electronics store?
