Any input would be appreciated folks.

#1 question. I heard a rotational squeak once when I first fired the SRT6. It stopped upon driving and I haven't heard it since. That was three months ago and I have driven the car at least ten times. I figured better safe than sorry but now I'm starting to wonder if I over reacted.

#2 I've ordered two of these pulleys and neither one matches my stock one even though they were supposed to. One is German Fabi Bilstein it's grooved and has the right I.D./ O.D. but it isn't wide enough to accommodate the belt. The other one is smooth and isn't anywhere close to the O.E.M. Any part numbers would be appreciated.
