Looks great!
I’m sure you already know this, but the garnish that comes with those tails maintains the line across the back.

I have the same JDM rear garnish as you but I’m running Valenti’s that don’t have any thing that matches with OEM. I did squirrel away a set of the tails that you have with this other garnish though.
