That's what I figured... so do I get the 71.5" then? All I know is when I replaced the crank pulley with the DMD, I put a new belt on it (a cheap-o), I don't remember running into this before, but outside of the age rib cracks on it, it fits like a glove and the tensioner is sitting right in the middle... but the size markings are worn off of it.
Since Autozone says 71.5" and Murray's says 71.5" and 72"... should I just shoot for the 71.5"? I was going to buy both and return one... but I'd rather know which is right for the car.
