I've seem some people apologize for reviving this thread. I see no need to apologize. I think this is good information to have.
I have a 2001 SES. I tried a 82 1/8" belt, and it fit around everything quite easily - without loosening the tensioner at all!
Next up was a 81 1/8" belt. It works, and it's kind of floppy. It didn't require very much tension on the tensioner to put it on, if you know what I mean.
I ordered the last, distributor closeout 80.5" Goodyear Gatorback from Rock Auto. I'm hoping that will do the trick.
