Ok the mounts look correct as well as the offsets on the holes. The one with the missing ear is the DRIVER side. Your "L" and "R" are correct being the "L" is the driver side. Did you have them on the wrong sides?
Look at the 340 mounts on the ebay auction to see how the rubber pads go on
I’m about to put them back on but I think the actual rubber mount was wrong, I found a pic that had the mounts on too and that’s what got me leaning towards that.
