Does anyone happen to have any HDS9t Gen3 units they are parting out? The threaded insert (used to mount via knobs on the U bracket) on mine came out, although they are pressed in, the hole is elongated and chewed up, looking for a replacement rear cover. Lowrance/Navico was no help on the phone. Still need to check if still in warranty when I get home, however it will be faster to swap it out myself, unit works fine otherwise.
