Just installed my new Goodyear Gatorback (PN 4060578). Literally took only 4 minutes start to finish (thanks to not having the OEM airbox in the way), and one minute to double check that the grooves were lined up. Perfect fit, right back into the proper zone on the tensioner.

Honestly it's not perfect. Not all the way to the left of the zone, which I would assume the OEM belt would be. I'd say the gatorback puts the indicator just to the right of dead center in the zone (which is small, 3-4mm). This is the correct part for the S2K though.
The next smallest "compatible" belt would be PN 4060575, with effective length 57.50" vs 57.80" for 4060578.
0.3 inches / 7.62 mm shorter. Probably too short.
An alternative would be a Dayco 5060578. Also $22 on Amazon, and sold at local stores like auto zone/advance auto. Effective length is 57.75", which is 1.26 mm shorter than the gatorback.
Napa's suggested belt, PN NBH 2506057 seems huge by comparison at 58.378".. but the PN doesn't match up with that length, so maybe the website is wrong.
Did a quick search but can't fine any data on the actual length of the OEM belt.

Got the old belt off, but had a hell of a time trying to get the Gator back belt in pn 4060578. Looked to be pretty short. Ultimately, gave up and put my old belt back on. Put the old belt to the new belt and they looked to be pretty similar in length (hard to be completely accurate). I'll try again when I have more time

Yea that's what I figured, so the gatorback is slightly larger. Still acceptable though, and the price is right.. could replace it almost 3x over for the price of OEM. First belt lasted me 177k, so I'll weight in again in another 59k

Get it on the bottom two pulleys, then loop it around the middle, then get it on the alternator, then slide it on your ratchet socket, move the tensioner (use extra force), and slide it on.

I'll definitely try that. From the distance of how off I was, I almost wanted to say they gave me the wrong belt, but with more and more tries, I did notice that it did seem to get a little closer. I didn't think I was THAT noob of a backyard mechanic:P
