well, I would say you are pretty safe. If not I am sure you can unload that somewhere on a celica web site or something.
03, Abyss monotone GT, 6 disk changer, moon and tunes, Cargo mat/nets, power package, side airbags, AEM Short Ram Intake, Borla exhaust , 35% tint all around, F1 strut tower brace, debadged, 17" Excel rims w/ federal ss595 tires.
I found it at http://www.iptmotorsports.com. Click on Toyota Celica GT to find the part. I was thinking that it would fit. I seen it posted some where before saying that the Celica GT engine cover is the same as the Vibe and Matrix base model engine covers whether it was this site or another but I just wanted to make sure. Let me know what you all think.
