Supercharge Belt Tensioner
Noticed that my supercharger belt tensoner is starting squeak. I've done some looking around and not coming up with much at all. I want to just replace the pulley as it still holds really well. Has anyone found a pulley that will work for this application?

There are some pretty nice aftermarket aluminum pulleys if you dont mind spending a bit. I believe Shardul sells them. You might want to consider replacing the whole tensioner though: they do weaken over time and the SC belt needs all the tension it can get (they're known to slip even with stock pullies). Gates 39354 is the OE equivalent without the MB markup.
