Does anyone have pics or know where I can get the 78-81 Iroc bumper/spoiler ?
I've seen it before and there was even a thread on it with some cool mods done to it on another board, but I can't remember where or which one

 

Are you thinking of 88-91???? because there was no iroc in 78-81

 

I found the thread on it !

there was not an IROC model like the 3 rd gen but the camaro was raced in IROC from the mid 70s until 90/91

 

I dotn know. Maybe try Classicindustries or year one they may know who would carry them.
