GM did make an idler pulley similar to this for the 67 Z..I had one a while back. I believe it came with PS cars that had 4:11 or 4:88 gears...but don't quote me..someone else probably knows better. </div></div>

that's funny, this car came with a 4:10 and a 4 core radiator (some say tied to a 4:10 car as a must have), so maybe it is factory? yes I doubt it, but I need to go look at it closer.
