Are you interested in older tech? I have an RT-328T NAV/COM on the shelf, with tray & connectors. I also have the R-443B glideslope receiver if you need it. The only thing I don't have is the VOR head, but I'll have that in October as I'm planning to have my mechanic pull both of mine at annual, one of which has the glideslope indicator.
