New to Forum, Help finding Part#

[Goveaeman]

Hi guys, i am new to this forum. I recently purchased a used 2008 Cadillac Escalade Base model. I so far have installed a Borla exhaust with down turn, Volant CAI, Viper Alarm and all bulbs have been changed to LEDs (6000k). I have also just purchase the Platinum Premium front Bumper assembly but need help finding additional parts and am at a loss. I have seen a few people on here do this upgrade but since i am new i still cannot PM anyone hahaha. I am looking for the following Parts:

-The top part of the Grill that is affixed to the hood
-Vents and chrome insert
-rear chrome part that is on tailgate that is half painted and half chrome

Thanks guys for your help
