Success! I might move to a different mount once available (or maybe the one
Squidget posted), but the ebay mount now works. The EOS mount squidget posted in this thread should also work with the spacers based on the measurement provided.
The ebay seller sent a longer post, 6.5” without counting threads vs the original 4.75” they had sent. It worked. Only complaint is that the plate rotates a little easier than I’d like fully tightened. That said, its not loose. On a short drive hitting speeds of 70mph it did not move. Its very adjustable and with how I positioned the plate on the bottom right mounting location, no interference with sensors. I did not experiment with other positions.

Theyll ask model of car. I’ll be sending my feedback to them shortly so they know what to send future buyers. All in all I consider it worth the $30 spent and recommend it. I will update the review here if I have any issues or change my opinion.
