I am amazed at how difficult these are to find. I went to a woodcraft store... nothing. I have catalogs from LMII, Carvin (who uses them) and Stewmac and there's not a trace. I figured that these would be an easy find since they are such a good idea, but tho my chagrin, they are not. I need to find brass threaded inserts like Carvin (only company I can think of) uses for holding down a control cavity. Neck ones were available from Moses, but those would be a bit too big for a control cover.
