Unfortunately they don't give an option for no A/C so we can't get a measurement. However, due to there no option for a part number that gives two options. First, take a string and route it around the pulleys and get a custom cut belt or one that fits that measurement. Second, just get an A/C pulley bypass pulley and use the stock belt. I always like to use the bypass pulley because it keeps everything where it is supposed to be and the same size belt so that you don't have to get one that compensates for the tensioner.

Let me know if you have questions on how to measure for a belt using the string and we can get more detail. Thanks
