Hi Robert
For all the leg parts I left as much material as possible, the left ear is not too low, if you look at the movie original it has the same spacing at the top showing some overlap compared to the right, you can tighten the screws a bit more they seem a bit loose on the round ear section, both left and right ear are trimmed right at the trim line can't leave anymore material but you can sand in strategic places to bring the hook section of the Right ear closer minimizing the gap, but like the original gaps are normal especially the right one seem to always have more gaps.
