Scosche and Metra make a lot of double din trim peices like that. The problem for everyone is if you don't have access to them all to try different ones out you have to just get the dash kit.
Imperial if it's not too much trouble maybe you can ask your installer if he remembers which one it was. That way others with Pioneers and base/sport/Nismo cars can buy one instead of the Metra kit.
Thanks again for the pic
