Not positive that I’m following your question. I don’t know that it matters how it mounts to the stem, top, bottom, or faceplate. I just need one that has a mount for a larger Garmin on top, and a quarter turn mount for a light/gopro, etc on the bottom.
K. Here are the ones mentioned:

Pretty sure that doesn’t have two mounts like OP asked and then clarified. It should have quarter mount on both sides of it.
Yeah. Not sure what OP wants. I saw the K-Edge non-link and assumed they needed to move from a bar-clamped mount to a stem mount. But the link is actually a stem faceplate mount for Enve stems with a Garmin up top and a GoPro below like the ones I linked. I missed the quarter turn clarification and was stuck on the cyclic reference which uses GoPro and cyqliq proprietary quarter turn mount. I was always afraid of twisting my Cycliq out of the mount as it was so easy to break.
ETA: after looking at David’s links i can see that maybe OP wanted the twist of Garmin to GoPro for easy removal. I just added some chargers in the garage to skip the after ride removals.
Yes, I think I worded my question poorly. I’m wanting a quarter turn on top and bottom that mounts on the stem because I can no longer use a bar mount. I also need it to be long enough to fit a 1030, I know that the standard Garmin mount does not have enough room - hence the reason they make an extended one and I believe also include it in the 1030 box.
I like the quarter turn on the bottom for easy removal of my Cycliq light/camera combo, my NiteRider light or occasionally my Virb. I do agree that the quarter turn on the Cycliq is suspect, I’ve already had one fail and was thankful for the tether.
I THINK the JRC you linked requires you to bolt the accessory on and off, which isn’t the end of the world. To your point, it may also be more secure. Just wanted recommendations/real life feedback as this is a bit of a one off accessory I suppose.
Here is a pic of my old 1030 mount with a VIRB under it if that helps at all.
