Hey there, I have a 98.5 SE 2.5L MTX... I am going to replace my alternator this weekend as well as the belt. When I called up Murray's Auto, they list 2 different belt sizes for the car WITH A/C. I do have A/C of course, but I don't understand why it shows up as 2 different sizes... they show the water pump of course, but the serpentine belt shows up as a 72" OR a 71.5"... Autozone has them listed as a 71.5". Which one is it? If it makes any difference at all (which I am 99% sure it doesn't), I have the DMD on the car. Any help would be greatly appreciated. Thank you!
