Most excellant customer service when it came to ordering the tweeter pods for my 2012 WRX. I also ordered a JDM Radio Trim bezel today because I can't stand the dash kit that came with my radio from Crutchfield.
Oh, and for what it is worth, the 19mm tweeters from the JL Audio C5-650 component set are a direct fit for the tweeter pods. You'll just need a little foam on the back side to wedge them into place.
EDIT - And another plus 1 for iaperformance with the JDM Radio Bezel:
