There are two different length belts available for the 2012. The pulley on the alternator may be the difference.

is one for no a/c and the other for the a/c?

I don't think it was for an AC delete unless the delete required an idler pulley to replace the AC compressor. Some GM cars have this.

The difference in the belt is about an inch. I always buy both and return the one I don't need.

Thanks for the pics. I really hope I don't have to take the pulley off the 2012. The shaft and nut are a rusted mess.
