Would like to find these mounts as used on the SCR 299 . The FT-388 is used to mount the LS-3 speaker to the table and the FT-389 is used to mount behind the the BC 312 & 342 that had shocks to provide additional stability for the receivers.

If some one has the FT-389 and doesn't wish to part with it..a pic of it and/or dimensional drawing would be much appreciated.

Thanks

Paul
