Does anyone have an old Narko MK12D or E, tray for sale? I have an MK12E radio, but no tray. I mainly need the spring lock side rails if that's all I can find, as I have the means to manufacture a back panel. My unit does not have Glideslope, but as I mentioned, I am open to many alternatives. I have scoured eBay, Texas Salvage, and many other sites but to no avail. Thanks!
